The HDMI Vendor-Specific Data block, defined as an opaque blob in the EDID
spec, is described in the HDMI spec.
Most of the extension fields are optional, so it doesn't translate well to a C
struct. For now callers need to manually fill the hdmi_vsd.data field.

You may want to clarify that this is the HDMI 1.4 thing, not the
HDMI 2.0 "HDMI Forum" thing.

vsdb is the acronym used by the specs. I would suggest a sed job
over the whole thing to align with that. The name of the function
is a bit vague. ..._set_ieee_oui_hdmi() ?

A comment explaining the 2 might be helful.

That's a good point. I just defined hdmi_ieee_oui as a constant
instead, which I thought would be nice, but in the end also brings
`extern` and memcpy.

size_t is a an odd choice for something that is not a size.
I would have also called it num_native_dtds or something.

The CEA extension can contain up to six DTDs and the base block
can have up to four. So we could make this assert even tighter:
assert(num_native_dtds <= (127 - 4 - data_block_size) / 18 + 4);
or something. But since that wouldn't check against the actual
number of dtds present maybe a bit pointless to do that.

Short Video Descriptors (SVDs, not to be confused with Vendor-Specific Data
blocks) describe CEA video formats supported by the monitor.

That only contains the base block. Are we leaving stack garbage in the
extension block?

I think we have an ARRAY_SIZE(). Although since we know these are bytes
maybe just a sizeof() would be good enough.
