SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

bios_emulator: Add vesa support and allow ROMs to be passed in as data

As well as locating the ROM on the PCI bus, allow the ROM to be supplied to
the emulator. Split the init up a little so that callers can supply their
own interrupt routines. Also allow a vesa mode to be provided, to be
selected once the BIOS run is complete.

pci: Add general support for execution of video ROMs

Some platforms don't have native code for dealing with their video
hardware. In some cases they use a binary blob to set it up and perform
required actions like setting the video mode. This approach is a hangover
from the old PC days where a ROM was provided and executed during startup.

Even now, these ROMs are supplied as a way to set up video. It avoids the
code for every video chip needing to be provided in the boot loader. But
it makes the video much less flexible - e.g. it is not possible to do
anything else while the video init is happening (including waiting hundreds
of milliseconds for display panels to start up).

In any case, to deal with this sad state of affairs, provide an API for
execution of x86 video ROMs, either natively or through emulation.

Introduce a header file for the BIOS emulator

We should have a public header so that users can avoid defining functions
themselves.
