drm/display: bridge_connector: Convert to drmm_connector_hdmi_init()

Browse source

Switch drm_bridge_connector to the new drmm_connector_hdmi_init()
signature.  The vendor, product, supported_formats and max_bpc values
now live in struct drm_connector_hdmi_funcs instead of being passed as
separate arguments.  This allows future HDMI 2.x capabilities to be
plumbed without growing the function's argument list.

Introduce the supported_hdmi_ver field in struct drm_bridge to let
bridges declare the HDMI specification version they comply with,
as well as max_tmds_char_rate to allow them to override the limit
inferred from that version.  This is particularly useful when handling
chip variants with different capabilities.

Additionally, add a warning in drm_bridge_add() if an HDMI bridge leaves
supported_hdmi_ver unset.  This alerts bridge drivers setting the
DRM_BRIDGE_OP_HDMI flag that they must also declare their supported HDMI
version.
