gpu: nvgpu: add broadcast address decode support for volta

With Volta we have more number of broadcast registers than previous chips
and we don't decode them right now in gr_gk20a_decode_priv_addr()

Add a new GR HAL decode_priv_addr() and set gr_gk20a_decode_priv_addr() for all
previous chips
Add and use gr_gv11b_decode_priv_addr() for Volta

gr_gv11b_decode_priv_addr() will decode all the broadcast registers and set
the broadcast flags apporiately

Define below new broadcast types
PRI_BROADCAST_FLAGS_PMMGPC
PRI_BROADCAST_FLAGS_PMM_GPCS
PRI_BROADCAST_FLAGS_PMM_GPCGS_GPCTPCA
PRI_BROADCAST_FLAGS_PMM_GPCGS_GPCTPCB
PRI_BROADCAST_FLAGS_PMMFBP
PRI_BROADCAST_FLAGS_PMM_FBPS
PRI_BROADCAST_FLAGS_PMM_FBPGS_LTC
PRI_BROADCAST_FLAGS_PMM_FBPGS_ROP
