PPC: Mac: Add debug prints in macio and dbdma code
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. Signed-off-by: Alexander Graf <agraf@suse.de>
