media: dm1105: 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, GFP_KERNEL can be used because it is called from
the probe function and no lock is taken.

The call chain is:
   dm1105_probe
      --> dm1105_hw_init
         --> dm1105_dma_map
