gpu: nvgpu: move gp106 specific clk_arbiter code into HAL

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.
