DW ethernet controller on AXS10x hangs sometimes after SW reset, so
add temporary quirk to reset DW ethernet controller IP core.
This quirk can be removed after axs10x reset driver
(see http://patchwork.ozlabs.org/patch/800273/)
or simple reset driver
(see https://patchwork.kernel.org/patch/9903375/)
will be available in upstream.

Hi Vineet,
Please specify if you have plans to add this patch to 4.14?
I'm asking because we mostly need this quirk in 4.14 - I hope generic simple
reset driver will be available in 4.15.
Thanks.

New code can't be added during the merge window ! I've applied it locally and it
will happen after rc1 is out !
