A bootmeth is a method of locating an operating system. For now, just add the uclass itself. Drivers for particular bootmeths are added later. If no bootmeths devices are included in the devicetree, create them automatically. This avoids the need for boilerplate in the devicetree files. Signed-off-by: Simon Glass <sjg@chromium.org>
