Commit d3d6b1bf85ae ("drm: bridge: dw_hdmi: fix preference of RGB modes
over YUV420") changed the order of the output bus formats, but missed to
update accordingly the affected comment blocks related to
dw_hdmi_bridge_atomic_get_output_bus_fmts().
Fix the misleading comments and a context related typo.
