We had mixed virtual and physical pointers in struct sysinfo_t. Some
being virtual by accident which led to problems when we tried to
reinitialize lib_sysinfo after relocating FILO (to get intentionally
virtual pointers valid again). I guess this didn't cause much trouble
before, as lib_get_sysinfo() was always called with physical addresses
being equal to their virtual counterparts.
For FILO, two possibilities seem practical: Either, have all pointers in
struct sysinfo_t physical, so relocation doesn't hurt. Or, have all
pointers virtual and call lib_get_sysinfo() again after relocation.
This patch goes the latter way, changing the following pointers for
situations where virtual pointers differ from physical:
.extra_version
.build
.compile_time
.compile_by
.compile_host
.compile_domain
.compiler
.linker
.assembler
.cb_version
.vdat_addr
.tstamp_table
.cbmem_cons
.mrc_cache
We could also just correct the accidentally virtual pointers. But, IMO,
this would lower the risk of future confusion.
Note 1: Looks like .version gets never set.
Note 2: .option_table and .framebuffer were virtual pointers but treated
like physical ones. Even in FILO, this led to no problems as
they were set before relocation.

uhci_reinit(), which get's exported through a new entry in hci_t:
hci_t.init().
Warning: This breaks code that relies on the current, special,
counterintuitive behaviour of uhci_reset(). If one wants a working host
controller after calling hci_t.reset(), he should call hci_t.init()
afterwards.

The SMM GNVS pointer is normally updated only when the
ACPI tables are created, which does not happen in the
resume path.
In order to restore this pointer it needs to be available
at resume time. The method used to locate it at creation
time cannot be used again as that magic signature is
overwritten with the address itself. So a new CBMEM ID
is added to store the 32bit address so it can be found
again easily.
A new function is defined to save this pointer in CBMEM
which needs to be called when the ACPI tables are created
in each mainboard when write_acpi_tables() is called.
The cpu_index variable had to be renamed due to a conflict

By the time we get to U-Boot, it's too late, so we need two extra bits - one
for vboot to tell coreboot to load the Option ROM and another for coreboot
to let vboot know it's been done.
This change sets up the communication, but doesn't act on it just yet.
Even with this CL we always load the VGA Option ROM, so there's nothing to
