	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.

2017-09-20	soc/intel/cannonlake: add rtc failure checking	Aaron Durbin
	In order to prepare for checking RTC failure in the early boot paths move the rtc failure calculation to pmutil.c and add a helper function to determine if failure occurred. In addition actually provide soc_get_rtc_failed() which properly indicates to the common code that RTC failure did occur in the cmos_init() path.
