According to CTA-861 specification, HDR static metadata data block allows a
sink to indicate which HDR metadata types it supports by setting the SM_0 t=
o
SM_7 bits. Currently, only Static Metadata Type 1 is supported and this is
indicated by setting the SM_0 bit to 1.

However, the connector->hdr_sink_metadata.hdmi_type1.metadata_type is alway=
s
0, because hdr_metadata_type() in drm_edid.c checks the wrong bit.

This patch corrects the HDMI_STATIC_METADATA_TYPE1 bit position.
