Dmitry Baryshkov	2d7202c6f3	drm/bridge: dw-hdmi-qp: replace mode_valid with tmds_char_rate ... Replace .mode_valid() callback with .hdmi_tmds_char_rate_valid(). It is more generic and is used in other mode validation paths. The rate validation for .mode_valid() will be performed by the drm_bridge_connector code.
