Fixes the following warnings:
./include/drm/drm_mode_config.h:841: warning: Incorrect use of
kernel-doc format:          * hdr_output_metadata_property: Connector
property containing hdr
./include/drm/drm_mode_config.h:918: warning: Function parameter or member 'hdr_output_metadata_property' not described in 'drm_mode_config'

./include/drm/drm_connector.h:1251: warning: Function parameter or member 'hdr_sink_metadata' not described in 'drm_connector'

Also adds some property documentation for HDR Metadata Connector
Property in connector property create function.
