Aparna Das 3e3ca8a761 gpu: nvgpu: vgpu: create vgpu common gr subctx unit
Add new unit vgpu subctx under common/vgpu/gr to manage
GR subcontext. This unit provides interfaces to allocate
and free subctx header.

Rename vgpu_subctx_gv11b* files to subctx_vgpu* files
renaming functions vgpu_gv11b_alloc_subctx_header to
vgpu_alloc_subctx_header and vgpu_gv11b_free_subctx_header
to vgpu_free_subctx_header which are called only if
NVGPU_SUPPORT_TSG_SUBCONTEXTS is enabled or free_channel_ctx_header
HAL op is set which is set only for gv11b for virtualization.

Also assign fifo HAL op free_channel_ctx_header to
vgpu_channel_free_ctx_header for vgpu gv11b which in turn
calls vgpu_free_subctx_header.
