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.

Therefore, allow that to happen.

This simplifies computing dram timings a lot.
This removes computation of rank size based on columns, rows,
banks,... and uses the information in SPD byte 31. The result of this
is that dimms with multiple asymmetric ranks are not supported
anymore. These however are very rare and most likely never tested on
this platform.
This also uses i2c block read instead of byte read to speed up the
raminit. The result is less time is being spend reading SPDs.
It still keeps smbus read byte as a backup if i2c block read were to

me_cleaner now allows setting a bit in the PCH straps - AltMeDisable
tells the ME to stop execution after BUP - disabling the 30 minute

This means the ME will not respond when we wait for an acknowledgement
about the DRAM being ready. The current code waits 5 seconds for a
response, that in this case, never comes.
If the ME is reporting opmode 2, don't delay or wait for a response
from the ME.
