drm/connector: Add drmm_connector_hdmi_init() with new signature

In preparation for providing HDMI 2.x source capabilities, move the
vendor, product, supported_formats and max_bpc parameters out of the
init function into struct drm_connector_hdmi_funcs, and add new
supported_hdmi_ver and supported_tmds_char_rate fields there as well.

Appending more HDMI-specific arguments to that function would not scale
well, hence introduce drmm_connector_hdmi_init() with the reduced
signature.

Additionally, add the max_tmds_char_rate field to struct
drm_connector_hdmi and use the supported HDMI version to determinate the
maximum TMDS character rate allowed by the specification.  Some
controllers, however, may support a lower rate than that version would
imply.  A non-zero supported_tmds_char_rate lets drivers override this
default with the actual controller capability.  A value of zero keeps
the limit inferred from supported_hdmi_ver.

Callers are converted in the following patches, while the old and now
renamed *_ini2() helper is removed at the end of the series.

No functional changes expected for existing callers.
