dm: reset: Allow reset_walk() to return
Add a new reset_walk_halt() function to cause a reset and then halt on failure. The reset_walk() function returns an error code. This is needed for testing since otherwise U-Boot will halt in the middle of a test. Signed-off-by: Simon Glass <sjg@chromium.org>
