I tend to disagree here (but perhaps you'll have other arguments to convince me otherwise): the GPIO used for PCIe reset is a completely board-specific thing. You can chose whatever GPIO you want, and each board can be different. Therefore, there is no reason to have such a pinmux configuration at the SoC level (.dtsi), it should be within the particular board that uses that pinmux configuration. This is a rule that we have applied to mvebu platforms in general, and which I believe is fairly common in many DTs.
