主题: [PATCH] drm/komeda: add NV12 format to support writeback layer type

When testing the d71 writeback layer function, the output format is set to NV12, and the following error message is displayed:

[drm:komeda_fb_is_layer_supported] Layer TYPE: 4 doesn't support fb FMT: NV12 little-endian (0x3231564e) with modifier: 0x0..

Check the d71 data manual, writeback layer output formats includes NV12 format.
