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

[Raveendra Talabattula]

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.

Komeda also leaves encoder->possible_clones unset, so it remains zero
for all encoders. As a result, DRM clone-mask validation can reject
writeback configurations because no encoder is advertised as
clone-compatible.

Patch 2 initializes encoder->possible_clones after encoder
registration, making the clone-mask setup explicit for registered
encoders.
