gpu: nvgpu: add support to get unicast addresses on volta

We have new broadcast registers on Volta, and we need to generate correct
unicast addresses for them so that we can write those registers to context image

Add new GR HAL create_priv_addr_table() to do this conversion
Set gr_gk20a_create_priv_addr_table() for older chips
Set gr_gv11b_create_priv_addr_table() for Volta

gr_gv11b_create_priv_addr_table() will use the broadcast flags and then generate
appriate list of unicast register for each broadcast register
