tegra power: Create a new power state called SimpleSuspend
This new power state corresponds to doing an LP2 like operation
at the end of Linux's suspend/resume sequence. When LP1/LP0
are working, we can replace SimpleSuspend with the real
Suspend/DeepSleep operations. The SimpleSuspend state
can also be used as a "sanity" state to assist in
debugging power issues.
