Konsta Holtta eb81d7d7e1 gpu: nvgpu: optimize map calls in patch smpc ...

Copy the necessary ctx patching prologues and epilogues from patch_write
to gr_gk20a_exec_ctx_ops next to mapping of gr ctx, around a loop that
applies patches multiple times, in order to optimize the number of
maps/unmaps on the channel's patch context.
