mb/google/brya/variant/hades: Reduce PEXVDD shutoff delay for Hades

For the sequenced controlled shutdown path, there's a 10ms delay
after the PEXVDD rail is disabled to permit discharge needed on
Agah/Proxima.

This can be dropped to 3ms for Hades designs Proto0 and forward.

Once Agah board is dropped, "if CONFIG" can be cleaned up/removed.
