r6040: 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 'r6040_open()', GFP_KERNEL can be used because
this is a net_device_ops' 'ndo_open' function. This function is protected
by the rtnl_lock() semaphore. So only a mutex is used and no spin_lock is
acquired.
