There's an occasional issue on machines which use CMOS for their
vbnv storage. The machine that just powers up from complete G3
would have had their RTC rail not held up. The contents of vbnv
in CMOS could pass the crc8 though the values could be bad. In
order to fix this introduce two functions:
1. vbnv_init_cmos()
2. vbnv_cmos_failed()
At the start of vboot the CMOS is queried for failure. If there
is a failure indicated then the vbnv data is restored from flash
backup or reset to known values when there is no flash backup.

Remove the unused support code from the old multi-device hudson
SD controller. The binaryPI blob contains the correct steps
for setting up SD and the public BKDG doesn't completely document
the controller.
The sd.c file was using device IDs not associated with the Stoney
Ridge APU. The hudson_enable() code removed was also looking for
incorrect device IDs and the PM_MANUAL_RESET register doesn't
behave as the source indicates.
The SD default settings may be overridden. Future improvements
may include a few Kconfig options and a weak call to the mainboard
for overriding additional defaults.

Add dedicated CAR setup and teardown functions and Kconfig
options to force their inclusion into the build. The .S files
are mostly duplicated code from the old cache_as_ram.inc file.
The .S files use global proc names in anticipation for use with
the Kconfig symbols C_ENVIRONMENT_BOOTBLOCK and POSTCAR_STAGE.
Move the mainboard romstage functionality into the soc directory
and change the function name to be compatible with the call
from assembly_entry.S. Drop the BIST check like other devices.
Move InitReset and InitEarly to bootblock. These AGESA entry
points set some default settings, and release/recapture the
AP cores. There are currently some early dependencies on
InitReset. Future work should include:
* Pull the necessary functionality from InitReset into bootblock
* Move InitReset and InitEarly to car_stage_entry() and out of
bootblock
- Add a mechanism for the BSP to give the APs an address
to call and skip most of bootblock and verstage (when
available) (1)
- Reunify BiosCallOuts.c and OemCustomize.c
(1) During the InitReset call, the BSP enables the APs by setting
core enable bits in F18F0x1DC and APs begin fetching/executing
from the reset vector. The BSP waits for all APs to also
reach InitReset, where they enter an endless loop. The BSP
sends a command to them to execute a HLT instruction and the
BSP eventually returns from InitReset. The goal would be to
preserve this process but prevent APs from rerunning early
code.
