video: Provide a command to list built-in images

Add a new 'video images' command which lists the graphical images that are compiled into U-Boot. Generally the only one is the logo. Series-to: concept Series-cc: heinrich 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.

Simon Glass	7695d711e6	acpi: bgrt: Move the BGRT image into the images directory Move the BGRT image to use the same video_image linker-list approach as the other embedded image. Move it into the drivers/video/images directory and rename it to 'bgrt.bmp' since we know it is an image. Drop the old bgrt Makefile rule as it is no-longer needed.

Simon Glass	aa9d53d696	video: Move the logo into the new video-images directory Move u_boot_logo.bmp into drivers/video/images and include it in the build. Make use of the new video_image_get() macro to obtain the logo. Drop the old SPLASH_...() macros.

Simon Glass	c4c6e183fd	video: Support a linker list of images It is inconvenient to have to access graphical images as independent symbols. Create a new rule which handles any file mentioned in drivers/video/images/Makefile For each graphical image, embed in the image and create a linker-list entry for it.
