gpu: nvgpu: enable CONFIG_NVGPU_VPR for all kernels

VPR functionality is split up as static VPR and VPR resize. Static VPR
is supported on all kernels. VPR resize is enabled only on 4.9 kernel.

Enable CONFIG_NVGPU_VPR unconditionally in Linux Makefile. Compile
VPR resize related functionality in nvgpu under the check for
Linux kernel version using new define NVGPU_VPR_RESIZE_SUPPORTED.
