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_output_metadata' not described in 'drm_connector' ./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.
