skylake: set and clear wake masks in S0 <-> S0ix transitions
In the S0 <-> S3 transition, Coreboot sends EC messages to set/clear the
wake masks when the SMI is invoked. For S0ix, EC sets and clears the
wake mask via this patch.
These functions are directly invoked from the state machine transition states.
During S0ix entry, the wake mask for lid open is enabled. During S0ix exit,
the wake mask for lid open is cleared. All pending events are also cleared
BRANCH=none
BUG=chrome-os-partner:48834
TEST=test lidopen in S0ix
