bootstd: Allow hunting for a bootdev by label
Add a function to hunt for a bootdev label and find the bootdev produced by the hunter (or already present). Add a few extra flags so that we can distinguish between "mmc1", "mmc" and "1" which all need to be handled differently. Signed-off-by: Simon Glass <sjg@chromium.org>
