drm/amd/display: Keep linebuffer pixel depth at 30bpp for DCE-11.0.
Testing on AMD Carizzo with DCE-11.0 display engine showed that
it doesn't like a 36 bpp linebuffer very much. The display just
showed a solid green.
Testing on RavenRidge DCN-1.0, Polaris11 with DCE-11.2 and Kabini
with DCE-8.3 did not expose any problems, so for now only revert
to 30 bpp linebuffer depth on asics with DCE-11.0 display engine.
Fixes: a316db72096044 ("drm/amd/display: Increase linebuffer pixel depth to 36bpp.")
