Tegra: sip: add VPR resize enabled check

The Memory Controller provides a control register to check
if the video memory can be resized. The previous bootloader
might have locked this feature, which will be reflected by
this register.

This patch reads the control register before processing
a video memory resize request. An error code, -ENOTSUP,
is returned if the feature is locked.
