gpu: nvgpu: gv100: fix PMA list alignment in ctxsw buffer

GV100 ucode is changed so that it expects LIST_nv_perf_pma_ctx_reg list in
ctxsw buffer to be 256 byte aligned but same change is not applied to other
chip ucodes

ADD new HAL (*add_ctxsw_reg_perf_pma) to configure PMA register list and
define a common HAL gr_gk20a_add_ctxsw_reg_perf_pma() for all other
chips except GV100

Define a separate HAL for GV100 gr_gv100_add_ctxsw_reg_perf_pma() and fix
the required alignment in this function
