gpu: nvgpu: move init_ltc_support sequence

Browse Source 
Currently, ltc fs_state is initialized during ltc init support. However,
ltc cbc_param and cbc_param2 registers do not seem to be providing
correct data if ltc.init_fs_state is called before fb.init_fs_state.
- Create fb.init_fb_support hal to initialize fb.
- Trigger init_fb_support before init_ltc_support.
