gpu: nvgpu: add HAL to get offset in gpccs segment

In gr_gk20a_find_priv_offset_in_buffer() we right now calculate
offset of a register in gpccs segment based on register address type

Separate out sequence to find offset in gpccs segment and move it to new API
gr_gk20a_get_offset_in_gpccs_segment()

Introduce new HAL gops.gr.get_offset_in_gpccs_segment() and set above API
to this HAL

Call HAL from gr_gk20a_find_priv_offset_in_buffer() instead of calling direct
API
