Jeetesh Burman 3e28e93540 Tegra: SiP: set GPU in reset after vpr resize
Whenever the VPR memory is resized, the GPU is put into reset first
and then the new VPR parameters are programmed to the memory controller
block. There exists a scenario, where the GPU might be out before we
program the new VPR parameters. This means, the GPU would still be
using older settings and leak secrets.

This patch puts the GPU back into reset, if it is out of reset after
resizing VPR, to mitigate this hole.
