drm/komeda: Set display/writeback clone masks

Browse source

Since commit 41b4b11da0 ("drm: Add valid clones check"),
all encoders attached to the same CRTC must advertise
each other through possible_clones.

Komeda creates one writeback connector per CRTC. Allow the writeback
encoder to be cloned only with encoders that can drive the same CRTC,
and update those encoders reciprocally.
