scsi: dc395x: Remove pci-dma-compat wrapper API

The legacy API wrappers in include/linux/pci-dma-compat.h should go away as
they create unnecessary midlayering for include/linux/dma-mapping.h API.
Instead use dma-mapping.h API directly.

The patch has been generated with the coccinelle script below.
Compile tested.
