Revert "Revert "ARM: tegra: pm: turn off VDEC partition in LP1""

This reverts commit 193e70e3a74bb167e4a443329dc0bd3cf0fcd7a0.

VDE partition has to be left on before entering LP0, otherwise
secure content playback may be corrupted after resuming from LP0.
So we unpowergate vde in the dependent change. This change turn
off vde partition specifically for LP1 case to save power.

Bug 1502013
