video/hdmi: Use hdmi_vendor_infoframe for the HDMI specific infoframe
We just got rid of the version of hdmi_vendor_infoframe that had a byte array for anyone to poke at. It's now time to shuffle around the naming of hdmi_hdmi_infoframe to make hdmi_vendor_infoframe become the HDMI vendor specific structure.
