gpu: nvgpu: add igpu support for clk_arbiter.
This patch constructs clk_arbiter specific code for gp10b as well as
gv11b and does the necessary plumbing in the clk_arbiter code. The
changes made are as follows.
1) Constructed clk_arb_gp10b.* files which add support for clk_arb
related HALS including the nvgpu_clk_arb_init and nvgpu_clk_arb_cb.
This doesn't have support for debugfs nor the VFUpdateEvent yet and
consequently no support for arb->notifications.
2) Added gpcclk specific variables corresponding to every gpc2clk in
a given clk_arb related struct.
3) Linux specific support_clk_freq_controller is assigned true in
platform_gp10b.c and platform_gv11b.c files.
4) Incremented the clk_arb_worker.put atomic variable during
worker_deinit so as to allow the worker thread to be stopped.
5) Added the flag clk_arb_events_supported as part of struct
nvgpu_clk_arb. This flag is used to selectively account for the extra
refcounting present in OS specific code i.e.
nvgpu_clk_arb_commit_request_fd. For igpus, the extra refcount is
reduced during nvgpu_clk_arb_release_completion_dev.
