[PATCH v1 1/1] arm64: zynqmp: Add output-enable pins to SOMs

[Frager, Neal]

> Now that the zynqmp pinctrl driver supports the tri-state registers, make sure that the pins requiring output-enable are configured appropriately for SOMs.

> Without it, all tristate setting for MIOs, which are not related to SOM itself, are using default configuration which is not correct setting.
> It means SDs, USBs, ethernet, etc. are not working properly.

> In past it was fixed through calling tristate configuration via bootcmd:
> usb_init=mw 0xFF180208 2020
> kv260_gem3=mw 0xFF18020C 0xFC0 && gpio toggle gpio at ff0a000038 && \
>  gpio toggle gpio at ff0a000038
