gpu: nvgpu: ctx_patch_write fixes

- Add update_patch_count parameter to ctx_patch_write_begin/end functions
  If True, the main_image_patch_count register will be updated. Previously,
  the patch count would be updated if the cpu_va for the graphics context
  was non-NULL, but this only works for sysmem (cpu_va is always 0 for vidmem)

- Remove unused patch parameter for the commit_global_timeslice functions
