ARM: rpi_b: detect board revision
Detect the board revision early during boot, and print the decoded
model name.
Eventually, this information can be used for tasks such as:
- Allowing/preventing USB device mode; some models have a USB device on-
board so only host mode makes sense. Others connect the SoC directly
to the USB connector, so device-mode might make sense.
- The on-board USB hub/Ethernet requires different GPIOs to enable it,
although luckily the default appears to be fine so far.
- The compute module contains an on-board eMMC device, so we could store
the environment there. Other models use an SD card and so don't support
saving the environment (unless we store it in a file on the FAT boot
partition...)
Set $fdtfile based on this information. At present, the mainline Linux
kernel doesn't contain a separate DTB for most models, but I hope that
will change soon.

Fix console functions for U-Boot API
Commit 709ea54 made a subtle change to the way the U-Boot API jump table
is set up. So at present putc(), getc(), tstc() and puts() do not work
correctly from functions that use the U-Boot API.
Previously these were set to the stdio functions, but these now take a
parameter specifying which stdio device to use. Instead, we should change
them to use the global functions which do not have a parameter.
This is a slight change in behaviour. The functions will now output to
all selected stdio devices - for example putc() will output a character to
all devices selected by stdout. However in most cases there is only one,
and it isn't necessarily incorrect behaviour anyway.
The API version is not changed since it is compatible with what was there
before.

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.
