ata_generic: drop hard coded DMA force logic for CENATEK
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.
