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.
