net: sky2: switch from 'pci_' to 'dma_' API

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

The patch has been generated with the coccinelle script below and has been
hand modified to replace GPF_ with a correct flag.
It has been compile tested.

When memory is allocated in 'sky2_alloc_buffers()', GFP_KERNEL can be used
because some other memory allocations in the same function already use this
flag.

When memory is allocated in 'sky2_probe()', GFP_KERNEL can be used
because another memory allocations in the same function already uses this
flag.
