soc/intel/apollolake: Clear RTC failure bit after reading it
This change ensures that the RTC failure bit is cleared in PMCON1
after cmos_init checks for it. Before this change, RPS was cleared
in dev init phase. If any reboot occurred before dev init stage
(e.g. FSP reset) then RPS won't be cleared and cmos_init will
re-initialize CMOS data. This resulted in any information like VBNV
flags stored in CMOS after first cmos_init to be lost.
BUG=b:72879807
BRANCH=coral
TEST=Verified that recovery request is preserved when recovery is
requested without battery on coral.
