Add PBL console support
This adds simple console support to the PBL which makes it possible to print more complex messages in the PBL than just strings or hex numbers. For now puts_ll is used to print the messages, so it depends on CONFIG_DEBUG_LL which makes it more a debugging option. However, this could be extended later to get regular output from the PBL if desired. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
