video: Provide a command to list built-in images

Browse Source 
Add a new 'video images' command which lists the graphical images that
are compiled into U-Boot. Generally the only one is the logo.

Cover-letter:
video: Tidy up embedded graphical images
U-Boot includes a few graphical images which are compiled in, such as
the logo and the BGRT logo used for EFI.

At present these are handled by a Makefile rule which looks for files
ending with '_logo.bmp'.

This series moves these into a new drivers/video/images directory and
puts them in a linker list, so it is possible to see what images are
available.

Adding a new image is simpler, just requiring the addition of the normal
'obj-y += file.bmp' rule.

This series also adds a new 'video' command which provides the existing
'setcurs' and 'lcdputs' as subcommands, along with documentation and
tests.

It also adds a more convenient 'write' subcommand.
