soc: qcom: rpmh-rsc: Set suppress_bind_attrs flag
[ Upstream commit 1a53ce9ab4faeb841b33d62d23283dc76c0e7c5a ]
rpmh-rsc driver is fairly core to system and should not be removable
once its probed. However it allows to unbind driver from sysfs using
below command which results into a crash on sc7180.
echo 18200000.rsc > /sys/bus/platform/drivers/rpmh/unbind
Lets prevent unbind at runtime by setting suppress_bind_attrs flag.
