ARC: [plat-axs103] Add temporary quirk to reset ethernet IP 

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.
