[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.
