[ARM] Collect Primecell PL01x-based debug implementations together
Several ARM machine implementations used a PL01x primecell compatible serial port for debugging purposes, and indepdently implemented the low level debug macros every time. Provide a common implementation and convert these implementations to use this version. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
