  Add the dynamic resolution support for video "capture_raw" device.
Otherwise it will capture the wrong image data if the width is
not 1920.

Fixes: e080f339c80a ("media: staging: media: starfive: camss: Add capture driver")

Hi

v2 forgot to synchronous description with v1. Now send a new version 3.

Best Regards
Changhuang
