net: sun: cassini: 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 'cas_tx_tiny_alloc()', GFP_KERNEL can be used
because a few lines below in its only caller, 'cas_alloc_rxds()', is also
called. This function makes an explicit use of GFP_KERNEL.
When memory is allocated in 'cas_init_one()', GFP_KERNEL can be used
because it is a probe function and no lock is acquired.
