net: neterion: s2io: 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 'init_shared_mem()' GFP_KERNEL can be used
because this flag is already used to allocate some memory in this function.

While at it, update some debug message to match the new function names.
