While this change may be fine for platforms based on Armada 3700 SoC,
it is not for the EspressoBin that has no reset GPIO for PCIe and
instead uses this pin to control the Ethenet switch.
I will re-send a series without this patch. I think it does not hurt to
keep the previous patch adding the pinmux setting in the
Armada-37xx.dtsi file even without using it, so I will drop only this
patch.
Thanks,
Miquèl
