video/hdmi: Add Unpack only function for DRM infoframe
It adds an unpack only function for DRM infoframe for dynamic range and
mastering infoframe readout.
It unpacks the information data block contained in the binary buffer into
a structured frame of the HDMI Dynamic Range and Mastering (DRM)
information frame.
In contrast to hdmi_drm_infoframe_unpack() function, it does not verify
a checksum.
It can be used for unpacking a DP HDR Metadata Infoframe SDP case.
DP HDR Metadata Infoframe SDP uses the same Dynamic Range and Mastering
(DRM) information (CTA-861-G spec.) such as HDMI DRM infoframe.
But DP SDP header and payload structure are different from HDMI DRM
Infoframe. Therefore unpacking DRM infoframe for DP requires skipping of
a verifying checksum.
v9: Add clear comments to hdmi_drm_infoframe_unpack_only() and
hdmi_drm_infoframe_unpack() (Laurent Pinchart)
