cr50: only enable rbox wakeup during sleep
Enable rbox wakeups before entering any form of sleep. Disable them
immediately on resume. Without rbox wakeups enabled during normal
operation, we don't need to worry about clearing them after every rbox
interrupt. In TOT we missed clearing the power button rbox wakeup. This
was causing cr50 to wake up immediately after entering regular sleep. It
caused a ton of pmu interrupts and prevented cr50 from staying asleep.
With this change cr50 enters enters sleep and deep sleep normally. It
only resumes when there's a real wakeup.
BUG=none
BRANCH=cr50
TEST=verify power button can still wake cr50 from sleep and deep sleep.
Run firmware_Cr50DeviceState with TOT
