Shikra (QCM2390) is a Qualcomm SoC based on the QCM2290 family that
reuses the same MDSS/DPU 6.5 hardware as QCM2290. This series enables
the display subsystem for Shikra by adding DT binding updates for MDSS,
DSI controller and DPU, arm64 defconfig enablement for the ILI7807S DSI
panel, and UBWC configuration mapping Shikra to qcm2290_data.
Driver and SMMU support are covered by the existing qcom,qcm2290-mdss
fallback compatible string — no separate drm/msm or IOMMU patches are
required.
Tested on Shikra CQM EVK board with ILI7807S DSI panel. Display
pipeline probes cleanly and panel renders correctly.

Changes in v2:
- Drop drm/msm/mdss: Shikra support patch; driver reuse is handled via
the qcom,qcm2290-mdss fallback compatible string (per Dmitry's review)
- Drop iommu/arm-smmu: Shikra SMMU client table patch; not required with
fallback compatible approach
- Fix UBWC config to map qcom,shikra to qcm2290_data instead of
no_ubwc_data; Shikra shares UBWC support with QCM2290
- Refactor series from 5 patches to 3 patches
- Link to v1: https://patch.msgid.link/20260603-shikra-display-v1-0-aeac1b94faa7@oss.qualcomm.com
