Deepak Nibade 4b8432a663 gpu: nvgpu: fix address table for GPCS_TPC6 broadcast conversion ...

In gr_gk20a_create_priv_addr_table() and gv11b_gr_egpc_etpc_priv_addr_table(),
we create a table of unicast addresses from broadcast addresses
For GPC boardcast addresses like NV_PGRAPH_PRI_EGPCS_ETPC6_SM_*, we generate
the table assuming there are 7 TPCs in all the GPCs

But this is incorrect in some cases like GV100 where GPC0/1 have only 6 TPCs
And hence we end up generating registers which do not exist

Fix this by explicitly checking the number of TPCs and ensuring that address
generated is belongs to valid TPC
