tlan: 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 'tlan_init()' GFP_KERNEL can be used because
it is only called from a probe function or a module_init function and no
lock is taken in the between.
The call chain is:
tlan_probe (module_init function)
--> tlan_eisa_probe
or
tlan_init_one (probe function)
then in both cases:
--> tlan_probe1
--> tlan_init
