Enable ATA DMA on pp5020 based players with ATA drives.

DMA is only used for reading because writing seems to be slower with DMA. Only requests which are cacheline aligned (16 bytes) will use DMA, so many requests will still use PIO at this point; a later change will align more reads. Part of FS#9708, original DMA code by Boris Gjenero (dreamlayers). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24405 a1c6a512-1295-4272-9138-f99709370657
