powerpc/mpc5200: Bestcomm fixes to ATA support
1) ata.h has dst_pa in the wrong place (needs to match what the BestComm
task microcode in bcom_ata_task.c expects); fix it.
2) The BestComm ATA task priority was changed to maximum in bestcomm_priv.h;
this fixes a deadlock issue experienced with heavy DMA occurring on
both the ATA and Ethernet BestComm tasks, e.g. when downloading a large
file over a LAN to disk.
