arm64: zynqmp: Disable Tri-state for SDIO
Since the zynqmp pinctrl driver now includes support for the
tri-state registers, ensure that the pins needing output-enable
are correctly configured for SOMs.
Currently, there is an issue with the detection of the MMC for
the SOM kv260, resulting in the following error:
ZynqMP> mmc dev 1
Card did not respond to voltage select! : -110
To address this problem, configure the SDIO pins for output-enable
to enable MMC detection.
