[PATCH v2 0/2] drm/komeda: Fix GLB_CORE_ID parsing and initialize encoder clone masks

Komeda currently decodes GLB_CORE_ID with bit definitions that do not
match the hardware register layout, which leads to incorrect hardware
version reporting.

Patch 1 fixes the GLB_CORE_ID field definitions so the reported product
version matches the hardware specification.

DRM clone-mask validation can reject Komeda display + writeback
configurations because the encoder pair attached to one CRTC does not
advertise the required reciprocal possible_clones relationship.

Patch 2 sets the display/writeback clone masks when the writeback
connector is created, making the clone relationship explicit for the
encoder pair attached to that CRTC.

Changes in v2:
- Patch 1: add a short GLB_CORE_ID layout comment and drop the redundant
  product-id mask and shift-by-zero change noted in review.
- Patch 2: replace the global encoder mask initialization with per-CRTC
  display/writeback clone-mask setup.
- Patch 2: include each encoder's own bit in possible_clones.
- Update patch 2 subject and cover letter text to match the localized fix.
