[PATCH] atm: remove deprecated use of pci api

[Quentin Lambert]

Replace occurences of the pci api by appropriate call to the dma api.

A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr)

@deprecated@
idexpression id;
position p;
@@

(
  pci_dma_supported@p ( id, ...)

  pci_alloc_consistent@p ( id, ...)

   when != pci_enable_device ( id )
(
  pci_dma_supported@p ( id, ...)
|
  pci_alloc_consistent@p ( id, ...)
)

@depends on !bad1@

...
+ , GFP_ATOMIC
  )
|
- pci_alloc_consistent@p ( id,
