radeonsi: Report multi-plane formats as unsupported

https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6693 added
NV12 lowering to PIPE_FORMAT_R8_G8B8_420_UNORM, which regressed some
video decode use cases in radeonsi, for example CtsDecodeTestCases in
android CTS. There are also discolored frames in video playback use
cases (i.e. youtube).

previously fixed similar issues in radeonsi. This change takes that a
step further to report any multi-plane format as unsupported.
