Seema Khowala 872be3a4ac gpu: nvgpu: ramin_big_page_size default val is set to 64kb ...

-MMU_CTRL_USE_PDB_BIG_PAGE_SIZE is set to TRUE and hence
 RAMIN_BIG_PAGE_SIZE should be set to 64KB i.e. val 1.
 By default this is set to 128KB i.e. val 0.
-This change will also fix an issue where perfbuffer_enable and
 nvgpu_init_hwpm function pass 0 as big page size while initializing
 inst_block and due to which ramin_big_page_size does not get updated
 to 64KB and remains set to unsupported 128KB value.
-Volta supports 64KB for big pages. Selecting 128KB for
 big pages results in an UNBOUND_INSTANCE fault.
