gpu: nvgpu: program ltc cg prod values after acr boot

Browse Source 
Separate nvgpu_cg_blcg/slcg_fb_ltc_load_enable function
into nvgpu_cg_blcg/slcg_fb_load_enable and
nvgpu_cg_blcg/slcg_ltc_load_enable.

Program fb slcg/blcg prod values during fb init and
program ltc slcg/blcg prod values after acr boot to
have correct privilege for ltc cg programming.

Update unit tests to have sperate blcg/slcg hal for
fb and ltc programming.
