[PATCH] drm/vkms: Add YUV410, YUV411, YVU410, and YVU411 support

[Renjun Wang]

Add support for the following planar YUV formats:
- DRM_FORMAT_YUV410
- DRM_FORMAT_YUV411
- DRM_FORMAT_YVU410
- DRM_FORMAT_YVU411

These formats are handled by the existing planar_yuv_read_line()
function, which correctly handles the subsampling defined in each
format's drm_format_info.

The YVU variants (YVU410, YVU411) are also added to
get_conversion_matrix_to_argb_u16() to ensure the U and V columns
are swapped correctly in the conversion matrix.
