EDID vendor IDs are always 3 characters long (4 with the terminating
0).  It doesn't make any sense to have a (possibly 8-byte) pointer
to the ID string in the quirk structure.

Requiring the first byte of the EDID base block header to be 0 means we
don't fix up as many transfer errors as we could.  Instead have the
callers specify whether it's meant to be block 0 or not, and
conditionally run header fixup based on that.

EFI doesn't typically make use of the legacy VGA ROM, but it may still be
configured to pass that through to a given video device. This may lead to
an inaccurate choice of default video device. Add support to efifb to pick

vga-switcheroo currently changes the default VGA device by fiddling with

will look for exactly the r-b-ness mentioned in the mode code.  This
