mb/google/zork: Fix pad configurations for wake signals
This change updates the pad configurations for wake lines as follows: 1. Pen eject wake signal needs to be configured as PAD_WAKE i.e. wake using GPIO controller block. This is because pen eject signal is not dual routed and the trigger filtering is set by the kernel driver differently for S0 and S3 wake. Hence, it cannot use SCI GEVENT and instead has to fall back to using GPIO controller wake. 2. All other wake signals (EC, trackpad, fingerprint) need to be configured as SCI. This allows OS to enable/disable wake from these sources if required. Example: powerd disables wake from trackpad when in tablet mode. Hence, all other wake sources use SCI.
BUG=b:159832123 TEST=Verified wake using pen eject and EC.
