ARM: tegra11x: residency time for different LP2 mode
Select CPU partition power gating only, non-CPU power gating, or
rail gating based on the required minimum residency and requested
sleep length.
The minimum residency for non-cpu power gating and rail-gating are
arbitrarily set in this change, they have to be characterized.
The minimum residency for non-cpu power gating shall always be
less than the minimu residency for rail gating.
Also fix a bug that prevents rail-gating
