This patch move of_pci_dma_configure() to a more generic
pci_dma_configure(), which can be extended by non-OF code (e.g. ACPI).

This has no functional change.

This one is needed since we are making use of the new of_dma_configure 
instead of the of_pci_dma_configure.

You are right. I'll update this one.

You are right. I'll remove this
