rpmsg: glink: Fix GLINK command prefix
[ Upstream commit 4e816d0318 ]
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.
