Using asm as it's done currently is unsafe because caller-saved registers
are not declared as clobbered.
Using real call is nicer.
regparm((1)) ensures that argument is passed in %eax as expected.

Ability to choose compatibility mode is interesting for testing payloads and

As per comments
"ide_legacy_combined # TODO: Does nothing since
generations, remove from sb code?"
The "combined" mode was removed. It wasn't used by any mobo and the code for
it is almost identical to IDE one other than few bits relating to interrupt

The memory initialization code is a work in progress for uboot, so we
only import the bits needed to get RAM up and running. Any refactoring
is cosmetic, and any functional refactoring should be done in separate
patches, and preferably, in coordination with the sunxi team.
Since it's not yet determined if we should initialize memory during
the bootblock or romstage, we don't add raminit to the build just yet.

Even though the Allwinner A10 is limited to a 24KiB bootblock, the
memory initialization takes only about 3KiB and leaves enough room for
an MMC or NAND driver, so init the memory early on. The advantage is
that we can eliminate complicated logistics of where to cache CBFS and
where to load the ramstage in SRAM.

Rather than having to track which bit in which register should be
cleared or set to gate or ungate the clock to a certain peripheral,
provide a simplified enum which encodes the register and bit. This
change comes with a function which decodes the enum and gates/ungates
the clock.
This also removes the register-dependent bitmasks for APB0 and APB1
gating registers.
