dm: video: Add a video uclass
U-Boot has separate code for LCDs and 'video' devices. Both now use a
very similar API thanks to earlier work by Nikita Kiryanov. With the driver-
model conversion we should unify these into a single uclass.
Unfortunately there are different features supported by each. This
implementation provides for a common set of features which should serve
most purposes. The intent is to support:
- bitmap devices with 8, 16 and 32 bits per pixel
- text console wih white on black or vice versa
- rotated text console
- bitmap display (BMP format)
More can be added as additional boards are ported over to use driver model
for video.
The name 'video' is chosen for the uclass since it is more generic than LCD.
Another option would be 'display' but that would introduce a third concept
to U-Boot which seems like the wrong approach.
The existing LCD and video init functions are not needed now, so this uclass
makes no attempt to implement them.

test/py: Implement pytest infrastructure
This tool aims to test U-Boot by executing U-Boot shell commands using the
console interface. A single top-level script exists to execute or attach
to the U-Boot console, run the entire script of tests against it, and
summarize the results. Advantages of this approach are:
- Testing is performed in the same way a user or script would interact
with U-Boot; there can be no disconnect.
- There is no need to write or embed test-related code into U-Boot itself.
It is asserted that writing test-related code in Python is simpler and
more flexible that writing it all in C.
- It is reasonably simple to interact with U-Boot in this way.
A few simple tests are provided as examples. Soon, we should convert as
many as possible of the other tests in test/* and test/cmd_ut.c too.
The hook scripts, relay control utilities, and udev rules I use for my
own HW setup are published at https://github.com/swarren/uboot-test-hooks.
