Subject: [PATCH] drm/vc4: Don't disable DSI clocks on component unload.

Git-commit: 2cbf59fd9026ac82b1c7429bb0de930a42d82063
Patch-mainline: v4.14-rc1
References: bsc#1051510
The clocks are enabled/disabled at encoder enable/disable time, not at
component load. Fixes a WARN_ON at boot if V3D fails to probe.
Fixes: 4078f5757144 ("drm/vc4: Add DSI driver")
