Several DRM drivers define their own local macros or use magic numbers for
the standard HDMI TMDS character rate limits. Maxime Ripard suggested that
instead these common rate constants could be included to a shared header.

This series introduces these constants to the <drm/display/drm_hdmi_helper.h>
header and replaces the local defined constants or magic numbers in drivers.

I split the changes as one patch per driver, so that these can be reviewed
individually and merged at their own pace.
