As we move to supporting other systems we need to get rid of assembly
where we can. The log2 function in src/lib is identical to the assembly
one (tested for all 32-bit signed integers :-) and takes about 10 ns
to run as opposed to 5ns for the non-portable assembly version. While speed
is good, I think we can spare the 15 ns or so we add to boot time
by using the C version only.

Fix multiple copy&paste errors and some other bugs in
devtree.asl. Redesign ENCM method to enter configuration mode
and set LDN by parameter. Reordered and commented some
statements to make the code a bit more readable. Add an ifdef
to enable never showing the keyboard controller as disabled,
which seems to cause bugs at least with some Linux kernels.
Remove keyboard controller IO regions from PS/2 mouse device
as e.g. Linux infers them from the keyboard controller device.

Instead of enable the device the device gets disabled. However after some time the serial line gets back, most likely some "enable resources" might fix it.
I'm attaching patch which somewhat fixes the problem and changes the function to look same in all superio code. Some boards even did not convert the dev->enabled to 0,1 values.

the prefix was introduced in the early v2 tree many years ago
because our old build system "newconfig" could not handle two files with
the same name in different paths like /path/to/usb.c and
/another/path/to/usb.c correctly. Only one of the files would end up
being compiled into the final image.
Since Kconfig (actually since shortly before we switched to Kconfig) we
don't suffer from that problem anymore. So we could drop the sb700_
prefix from all those filenames (or, the <componentname>_ prefix in general)
- makes it easier to fork off a new chipset
- makes it easier to diff against other chipsets
- storing redundant information in filenames seems wrong

W83627DHG:
- Add proper "virtual LDN" handling for the LDNs that need it (i.e., those
that don't have their "enable" bit in bit 0 of the 0x30 register).
- Fix various I/O masks in the pnp_dev_info[] array as per
datasheet. Add missing PNP_IRQ0 to the W83627DHG_ACPI LDN.
W83627EHG:
- Similar to W83627DHG, improve the "virtual LDN" setup a bit (it was
mostly implemented already, though).
- Add missing PNP_IRQ0 to the W83627EHG_ACPI LDN.
Also: Fix up devicetree.cb of all boards using W83627DHG/W83627EHG to adapt
for the virtual LDNs.
include/device/pnp.h: Add comment that 'function' (which refers to the
LDN and should probably be renamed later) has to be at least 16 bits
wide. In theory LDNs could use u8, but due to the virtual LDN info being
encoded in the "high byte" of 'function' it must be at least u16.
asrock/939a785gmh/romstage.c: Drop unused GPIO6_DEV.
ibase/mb899/romstage.c: Use DUMMY_DEV instead of a specific LDN (serial
port 1 in this case) to avoid confusion. The global registers
manipulated there are accessible from any LDN.

The only difference is that the "G" version is in a Pb-free package, which
is not relevant from a programmer's view.
We keep W83627THG (and drop W83627THF) because:
- The W83627THF had a CIR device / LDN which doesn't actually exist.
- The W83627THF had no GPIO2, GPIO3 LDNs (were commented out).
- The W83627THF didn't use the PNP_MSC0/1 which is needed/used by boards.
This also fixes an issue on MSI MS7135's devicetree.cb:
device pnp 4e.6 off end # XXX keep allocator happy
The line above can be (and is) removed, as it was only needed due to the
incorrect CIR LDN in the W83627THF.
In the iwill/dk8x target: Drop incorrect LDNs 4 and 6, add 0xb.

at the same time let the user specify sources instead
of object files:
- objs becomes ramstage-srcs
- initobjs becomes romstage-srcs
- driver becomes driver-srcs
- smmobj becomes smm-srcs
The user servicable parts are named accordingly:
ramstage-y, romstage-y, driver-y, smm-y
Also, the object file names are properly renamed now, using
.ramstage.o, .romstage.o, .driver.o, .smm.o suffixes consistently.
Remove stubbed out via/epia-m700 dsdt/ssdt files - they didn't
easily fit in the build system and aren't useful anyway.

This reverts commit eb7bb49eb5b48c39baf7a256b7c74e23e3da5660.
Stepan pointed out that "s" means string, which makes the following statement
in this commit message invalid: "Since we either have reserved space (which
we shouldn't do anything with in these two functions), an enum or a
hexadecimal value, unsigned int seemed like the way to go."

To ease some of my debugging pain on the unichrome, i decided i needed to
move FB size selection into cmos, so i could test a size and then reset it
to the default after loading this value so that the next reboot uses the
(working) default again. This meant implementing set_option in parallel to
get_option.
get_option was then found to have inversed argument ordering (like outb) and
passing char * and then depending on the cmos layout length, which made me
feel quite uncomfortable. Since we either have reserved space (which we
shouldn't do anything with in these two functions), an enum or a
hexadecimal value, unsigned int seemed like the way to go. So all users of
get_option now have their arguments inversed and switched from using ints
to unsigned ints now.
The way get_cmos_value was implemented forced us to not overlap byte and to
have multibyte values be byte aligned. This logic is now adapted to do a
full uint32_t read (when needed) at any offset and any length up to 32, and
the shifting all happens inside an uint32_t as well. set_cmos_value was
implemented similarly. Both routines have been extensively tested in a
quick separate little program as it is not easy to get this stuff right.
build_opt_tbl.c was altered to function correctly within these new
parameters. The enum value retrieval has been changed strol(..., NULL, 10)
to stroul(..., NULL, 0), so that we not only are able to use unsigned ints
now but so that we also interprete hex values correctly. The 32bit limit
gets imposed on all entries not marked reserved, an unused "user_data" field
that appeared in a lot of cmos.layouts has been changed to reserved as well.
