5.4-stable review patch. If anyone has any objections, please let me know.

From: Bjorn Andersson quic_bjorande@quicinc.com
[ Upstream commit 4e816d0318fdfe8932da80dbf04ba318b13e4b3a ]
The upstream GLINK driver was first introduced to communicate with the RPM on MSM8996, presumably as an artifact from that era the command defines was prefixed RPM_CMD, while they actually are GLINK_CMDs.
Let's rename these, to keep things tidy. No functional change.
