[PATCH] x86/PCI: sta2x11: switch from 'pci_' to 'dma_' API

[Christophe JAILLET <christophe.jaillet@wanadoo.fr>]

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below.

It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.

It has been compile tested.
