gpu: nvgpu: use vpr resize API
This patch adds nvgpu API in linux and qnx to query vpr resize.
The new API nvgpu_is_vpr_resize_enabled() is used in
nvgpu_submit_channel_gpfifo().
Previously, if non-deterministic channel has timeout disabled and
GPU cannot railgate on some platform, then channel doesn't power ref
count and results in video freeze. This requires non-determinstic
channel job tracking to be enabled if vpr resize is supported or if GPU
can railgate.
