On boards without console recording these function are currently missing. It is more convenient for them to be present but to return dummy values. That way if we know that a test needs recording, we can check if it is available, and skip the test if not, while avoiding #ifdefs. Update the header file according and adjust console_record_reset_enable() to return an error if recording is not available. Signed-off-by: Simon Glass <sjg@chromium.org>
