It's the same stuff as in the new child devices.

This lets us use the verbatim copy of the kernel intel_vbt_defs.h file
after kernel commit 058727ee8d9a ("drm/i915/bios: amend edp block based
on intel_vbt_decode").

Retain the legacy definition for the obsolete child device block, at
least for now. No functional changes.

Copy over most of intel_vbt_defs.h, and use everything that matches with

For reasons unknown, we have two copies of the struct. Deduplicate.

Fix decoding of the start of the child device structure. I had
accidentally duplicated the "device class/type" member and forgot to
include the add-in offset later. Fortunately both were two byte fields
so they effectively cancelled each other out and thus the remainder of
the child device structure was being decoded correctly. But of course
anything sitting between these two fields was being decoded incorrectly.

Knowing how were trasmitting the data is pretty important, so let's
dump out the video transfer mode and pixel overlap for DSI.

Decode the PSR block (9) from VBT. Looks like the same block ID may have
been used for something else in the past, so a version check is also
needed.
The wakeup times part is still up in the air due to the spec not knowing
what it's saying, but let's do something that makes at least some sense
given the VBTs currently out there in the wild.

New stuff has been added to the end of the child device block at various
times, so using a hardcoded size for the block is a bad idea.
Fortunately the size of the block is listed in the VBT just before the
blocks themselves, so grab it from there.

All the somewhat recent VBT specs and the kernel have different format
for the eDP block than what the tool decodes. What the tool does *may*
be correct for really old VBT, but I have no specs or other reference to
suppor this. Just do what the kernel does, that's what we're interested
in anyway.

Some of our device class defines were incorrect, and we were missing
several recent ones, so fix those up and dump more child device data if
we have it.
