soc/amd/common: add gpio subsystem event reporting

In order to log gpio events for wake purposes the state
of the gpio subsystem should be snapshotted. Add the ability
to capture state of gpio subystem as well as saving up to 16
gpios that indicate their wake status.

Likewise, provide the eventlog additions based on state.
