Group some variables based on their sizes to reduce hole and avoid padding.
On x86_64, this shrinks the size of 'struct hdmi_avi_infoframe'
from 68 to 60 bytes.
It saves a few bytes of memory and is more cache-line friendly.
This also reduces the union hdmi_infoframe the same way.

Similar to HDMI, DP uses audio infoframes as well which are structured
very similar to the HDMI ones.
This patch adds a helper function to pack the HDMI audio infoframe for
DP, called hdmi_audio_infoframe_pack_for_dp().
hdmi_audio_infoframe_pack_only() is split into two parts. One of them
packs the payload only and can be used for HDMI and DP.
Also constify the frame parameter in hdmi_audio_infoframe_check() as
it is passed to hdmi_audio_infoframe_check_only() which expects a const.

According to the CTA 861.G spec, HDMI_STATIC_METADATA_TYPE1 is
not 1, but zero, so fix this enum.
While this doesn't cause problems in the kernel yet, as the
constant isn't actively used by drivers yet, it did create
confusion while debugging HDR problems in yours truly, and
also potential bugs in userspace components, as the wrong
enum propagates to components, e.g., like it did already
into intel-gpu-tools (tests/kms_hdr.c) or is used as wrong
reference when writing future new userspace HDR components
like compositors.

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.

Let's make the infoframe pack functions usable with a const infoframe
structure. This allows us to precompute the infoframe earlier, and still
pack it later when we're no longer allowed to modify the structure.
So now we end up with a _check()+_pack_only() or _pack() functions
depending on whether you want to precompute the infoframes or not.
The names aren't great but I was lazy and didn't want to change all the
drivers.
