gpu: nvgpu: pass alloc_gpfifo args to gk20a_channel_alloc_gpfifo

Browse Source 
The patch defines 'struct nvgpu_gpfifo_args' to be filled
by alloc_gpfifo(_ex) ioctls and passed to the
gk20a_channel_alloc_gpfifo function. This is required as a
prep towards having the usermode submission support in the
core channel core.
