Subject: [PATCH] dmaengine: 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.
It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.
It has been compile tested.

If needed, see post from Christoph Hellwig on the kernel-janitors ML:
https://marc.info/?l=kernel-janitors&m=158745678307186&w=4
This patch is mostly mechanical and compile tested. I hope it is ok to
update the "drivers/dma/" directory all at once.
