gpu: nvgpu: add platform control for gc off

Browse Source 
The GC-OFF feature shall be available only for selective
dGPUs like Volta, etc. To enable this, add a platform flag
to control GC-OFF feature for a given dGPU.

If GC-OFF is not enabled for a dGPU, EPERM error will be
returned by kernel interfaces.
