gpu: nvgpu: remove broken force_pramin feature

The forced PRAMIN reads and writes for sysmem buffers haven't worked in
a while since the PRAMIN access code was refactored to work with
vidmem-only sgt allocs. This feature was only ever meant for testing and
debugging PRAMIN access and early dGPU support, but that is stable
enough now so just delete the broken feature instead of fixing it.
