fddi: switch from 'pci_' to 'dma_' API 

In [1], Christoph Hellwig has proposed to remove the wrappers in
include/linux/pci-dma-compat.h.

Some reasons why this API should be removed have been given by Julia
Lawall in [2].

A coccinelle script has been used to perform the needed transformation
Only relevant parts are given below.

It has been compile tested.
