This change extends the compatible strings for the Shikra (QCM2390) display subsystem to include QCM2290 fallbacks.

Shikra is a Qualcomm SoC derived from the QCM2290 family and reuses the same MDSS/DPU 6.5 display hardware. The earlier change introduced Shikra-specific compatible strings; this update complements that by adding QCM2290 compatibles as fallback entries.

By following the standard compatible fallback pattern (specific → generic), the display drivers can match against the shared QCM2290 implementation where applicable, avoiding duplication and ensuring better reuse of existing driver support.
No functional change is intended beyond enabling broader driver compatibility.

Shikra reuses the same MDSS/DPU 6.5 hardware as QCM2290. Extend
the existing qcm2290 bindings to cover Shikra by adding fallback
compatible chains for MDSS, DPU and DSI controller nodes rather
than introducing a separate binding file.

Add UBWC configuration for the Shikra platform. Shikra shares the
same hardware as QCM2290 (Agatti), so reuse qcm2290_data for the
UBWC settings
