Seeing accessing BAR registers can be dangerous and break the driver, we don't want unpriviliged users to have this ability. Therefore, for the local and remote GAS access MRPC commands, the requesting process should need CAP_SYS_ADMIN. Priviligded processes will already have access to the bar through the sysfs resource file so this doesn't give userspace any capabilities it didn't already have.
