dma: hisi_dma: switch from 'pci_' to 'dma_' API

Commit Message

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

The patch has been generated with the coccinelle script below.

-    pci_set_dma_mask(e1, e2)
+    dma_set_mask(&e1->dev, e2)

-    pci_set_consistent_dma_mask(e1, e2)
+    dma_set_coherent_mask(&e1->dev, e2)

While at it, some 'dma_set_mask()/dma_set_coherent_mask()' have been
updated to a much less verbose 'dma_set_mask_and_coherent()'.

This type of patches has been going on for a long time, I plan to 
clean it up in the near future. If needed, see post from 
Christoph Hellwig on the kernel-janitors ML:
