scsi: megaraid: 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. And has
been hand modified to replace each GFP_ with a correct flag depending upon
the context. Compile tested.
