ARM: tegra: remove vpr refetch call from kernel
Remove vpr refetch from kernel
Do VPR refetch in below sequence :
- first force idle the GPU
- then do SMC call to update VPR size
- unidle the GPU
- while GPU is resuming from rail gated, it will fetch latest
VPR settings on its own
- Hence there is no need to explicitly call vpr_refetch call
in kernel
