Subject: [PATCH] drm/msm/a6xx: Only print the GMU firmware version once

From: Konrad Dybcio <konrad.dybcio@....qualcomm.com>

We only fetch it once from userland, so let's also only notify the
user once and not on every runtime resume.

As you can notice by the tags chain, more than one user found this
annoying.
