dmaengine: idxd: Simplify code and axe the use of a deprecated API

The wrappers in include/linux/pci-dma-compat.h should go away.

Replace 'pci_set_dma_mask/pci_set_consistent_dma_mask' by an equivalent
and less verbose 'dma_set_mask_and_coherent()' call.

Even if the code may look different, it should have exactly the same
run-time behavior.
If pci_set_dma_mask(64) fails and pci_set_dma_mask(32) succeeds, then
pci_set_consistent_dma_mask(64) will also fail.
