ata_generic: drop hard coded DMA force logic for CENATEK

Browse Source 
Commit 1529c69adc (ata_generic: implement ATA_GEN_* flags and force
enable DMA on MBP 7,1) implemented ATA_GEN_FORCE_DMA for forcing DMA
mode and applied it to CENATEK but forgot to remove the original hard
coded logic.  This is removal of redundant logic and doesn't affect
correctness.
