Subject: drm/vc4: hdmi: Depends on CONFIG_PM
Git-commit: 72e2329e7c9bbe15e7a813670497ec9c6f919af3
Patch-mainline: v6.0-rc3
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
We already depend on runtime PM to get the power domains and clocks for
most of the devices supported by the vc4 driver, so let's just select it
to make sure it's there.
