Revert "arm64: dts: qcom: x1e80100: enable OTG on USB-C controllers"
This reverts commit f042bc234c2e00764b8aa2c9e2f8177cdc63f664.
A recent change enabling role switching for the x1e80100 USB-C
controllers breaks UCSI and DisplayPort Alternate Mode when the
controllers are in host mode:
ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: PPM init failed, stop trying
As enabling OTG mode currently breaks SuperSpeed hotplug and suspend,
and with retimer (and orientation detection) support not even merged
yet, let's revert at least until we have stable host mode in mainline.
