[PATCH v12 02/25] drm/display: hdmi-state-helper: Use default case for unsupported formats

[Nicolas Frattaroli <nicolas.frattaroli@collabora.com>]

Switch statements that do not handle all possible values of an
enumeration will generate a warning during compilation. In preparation
for adding a COUNT value to the end of the enum, this needs to be dealt
with.

Add a default case to sink_supports_format_bpc's DRM_OUTPUT_COLOR_FORMAT
switch statement, and move the log-and-return unknown pixel format
handling into it.

No functional change.
