mb/google/zork: Set S0IX_SLP_L high in S0, low in S3
This is used as a signal to show the system state. It hadn't been used
up to this point as we're not currently using S0i3, but the fingerprint
sensor will use it to go into a low power mode, so set it appropriately
on Trembyle. Dalboz devices don't use the FPMCU, but set there as well
so that the state matches.
BUG=b:174695987
TEST=Verify GPIO state in S0 and S3 with the EC
