sata_inic162x: use IDMA for ATAPI commands
Use IDMA for ATAPI commands. Write and some misc commands time out
when executed using ATAPI_PROT_DMA but ATAPI_PROT_PIO works fine. As
PIO is driven by DMA too, it doesn't make any noticeable difference
for native SATA devices. inic_check_atapi_dma() is implemented to
force PIO for those ATAPI commands.
After this change, sata_inic162x issues all commands using IDMA.
