Revert "ARM: tegra: pm: turn off VDEC partition in LP1"
This reverts commit ff4983e5bf793f1abdd8e325abdbd254256f80e3.
There is no need to powergate VDE specifically in LP1 now since
the dependent change has removed the unpowergating statement in
avp suspend callback. VDE powergating in LP1 will be taken care
of in the common suspend callback.
