sfc fixup patch

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

Hi Dave, Shradha !

While merging some EEH changes, I noticed a breakage in the SFC driver
due to it using an API we didn't mean driver to use directly and that
is going away. I've done this small fixup patch, any objection to me
sticking it in the original series (as to avoid bisection breaks)
before I send it to Linus ?

Cheers,
Ben.

net/ethernet/sfc: Don't use of_node_to_eeh_dev()

This is deprecated, it forces the driver to hop via the OF node
that may or may not exist, instead use pci_dev_to_eeh_dev() which
is simpler.
