Add missing compatible strings from 4.9/960-add-rasbperrypi-compatible.patch, using upstream names for compute modules. Add extra patch to enable the LEDs on lan78xx.

+Subject: [PATCH 204/454] drm/vc4: Move the DSI clock divider workaround closer
+ to the clock call.
+
+We want the adjusted_mode->clock to be the actual clock we're
+expecting to program, so that consumers see the right values for clock
+and vrefresh.
