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.
