Currently, clock arbiter code is extensively using dgpu specific
implementation. This patch restructures the clk_arbiter code and moves
gp106 specific code into HAL. Following changes are made in this patch
1) clk_domain_get_f_points is now invoked via HAL for gp106 i.e.
g->ops.clk.clk_domain_get_f_points.
2) moved nvgpu_clk_arb_change_vf_point and other related static
functions to clk_arb_gp106.c.
3) Instead of only checking if get_arbiter_clk_domain is empty, a
check for support_clk_freq_controller is also added. This is to enable
the clk_arbiter based on support from both the OS and the chips.

Reorganize HAL initialization to remove inheritance and construct
the gpu_ops struct at compile time. This patch only covers the clk
and clk_arb sub-module of the gpu_ops struct.
Perform HAL function assignments in hal_gxxxx.c through the
population of a chip-specific copy of gpu_ops.

Add clock arbiter skeleton with support of clock sessions,
notifications on clock changes, request numbering, and asynchronous
handling of clock requests. Provides minimum behaviour to allow
unit tests implementation. Actual arbitration and clock settings
will be done separately. For now, dummy arbiter keeps last
requested target mhz. Actual arbiter may move to a lockless
implementation.
