fix: panel-cwu50 timing fix from Rex's kernel - native 720x1280 mode

Swap H/V display mode to native panel resolution (720x1280) instead of
rotated (1280x720). The DRM/KMS pipeline handles rotation via connector
orientation property. Setting wrong horizontal resolution caused DSI
controller to send extra pixels per line, resulting in horizontal
repetition.

Add DCS-based panel detection in init_sequence2 as supplemental check.

Based on ak-rex/ClockworkPi-linux rpi-6.12.y branch panel-cwu50.c.

Replaces old 0008 patches (DSI_INIT0, BURST removal) that didn't fix
the issue.
