Subject: [PATCH v5 12/17] drm/rockchip: vop2: Recognise 10/12-bit YUV422 as
 YUV formats

The Rockchip VOP2 video output driver has a "is_yuv_output" function,
which returns true when a given bus format is a YUV format, and false
otherwise.

This switch statement is lacking the bus format used for YUV422 10-bit,
as well as the bus format used for YUV422 12-bit.

Add MEDIA_BUS_FMT_YUYV10_1X20 and MEDIA_BUS_FMT_YUYV12_1X24 to
is_yuv_output's switch cases to resolve this.

Fixes: 604be85547ce ("drm/rockchip: Add VOP2 driver")
