The RTC functionality provided by the include is specific to x86, but
is not used in these files.

The previous code does a full flush of the uart after every character.
Unfortunately, this can cause transmission delays on some serial
ports.
This patch changes the code so that it does a flush at the end of
every printk instead of at the end of every character. This reduces
the time it takes to transmit serial messages (up to 9% on my Asrock
e350m1 board). It also makes the transmission time more consistent
which is important when performing timing tests via serial
transmissions.

coreboot made it kind of complicated to print a character on serial. Not quite
as complicated as UEFI, but too much for a good design. Fix it.

while others dislike them being extra commits, let's clean them up once and
for all for the existing code. If it's ugly, let it only be ugly once :-)

It's basically done with the following script and some manual fixup:
VARS=`grep ^define src/config/Options.lb | cut -f2 -d\ | grep -v ^CONFIG | grep -v ^COREBOOT |grep -v ^CC`
for VAR in $VARS; do
find . -name .svn -prune -o -type f -exec perl -pi -e "s/(^|[^0-9a-zA-Z_]+)$VAR($|[^0-9a-zA-Z_]+)/\1CONFIG_$VAR\2/g" {} \;
done

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.

- drop srm console code (not supported anyways)
- make internal uart8250 console functions static
- split vsprintf.c into vsprintf.c and vtxprintf.c
