PPC: Mac: Add debug prints in macio and dbdma code

Browse source 
The macio code is basically undebuggable as it stands today, with no
debug prints anywhere whatsoever. DBDMA was better, but I needed a
few more to create reasonable logs that tell me where breakage is.

Add a DPRINTF macro in the macio source file and add a bunch of debug
prints that are all disabled by default of course.
