MLK-19419: drm: imx: dcss: Add linear modifier support for all formats

Tiled formats are supported only for YUV420 semi-planar formats.
However, the other formats should support at least the LINEAR modifier.
Some userspace app may pass on framebuffers with the linear modifier
attached and, currently, this is rejected for YUV422 and RGB formats.

This patch fixes that.
