net: bcmgenet: fix WAKE_FILTER resume from deep sleep

The WAKE_FILTER logic can only wake the system from the standby
power state. However, some systems that include the GENET IP
support deeper power saving states and the driver should suspend
and resume correctly from those states as well.

This commit set squashes a few issues uncovered while testing
suspend and resume from these deep sleep states.
