Christophe's patch is part of a larger effort of removing the use of the
deprecated pci-dma-compat API.

All patches have been reviewed on the mailing list, and have been in the

fpga: dfl: pci: Remove usage of the deprecated "pci-dma-compat.h" API

In [1], Christoph Hellwig has proposed to remove the wrappers in
include/linux/pci-dma-compat.h.

Some reasons why this API should be removed have been given by Julia
Lawall in [2].

A coccinelle script has been used to perform the needed transformation.
It can be found in [3].

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.

The explicit 'ret = -EIO;' has been removed because
'dma_set_mask_and_coherent()' returns 0 or -EIO, so its return code can be
used directly.
