net: packetengines: 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 GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'hamachi_init_one()' (hamachi.c), GFP_KERNEL
can be used because it is a probe function and no lock is acquired.

When memory is allocated in 'yellowfin_init_one()' (yellowfin.c),
GFP_KERNEL can be used because it is a probe function and no lock is
acquired.
