soc/intel/cannonlake: Fix GEN_PMCON bit checks
CNL PCH has PWR_FLR, SUS_PWR_FLR and HOST_RST_STS bits in GEN_PMCON_A
and so this change updates the check for these bits to use GEN_PMCON_A
instead of GEN_PMCON_B.
BUG=b:128482282
TEST=Verified that prev_sleep_state is reported correctly when booting
from S5.
