arm64: dts: imx8mn-tqma8mqnl-mba8mx-usbot: fix coexistence of output-low and output-high in GPIO

Browse source

[ Upstream commit c771d311b1 ]

Fix the issue where both 'output-low' and 'output-high' exist under GPIO
hog nodes  (rst_usb_hub_hog and sel_usb_hub_hog) when applying device
tree overlays. Since /delete-property/ is not supported in the overlays,
setting 'output-low' results in both properties being present. The
workaround is to disable these hogs and create new ones with 'output-low'
as needed.

Fix below CHECK_DTBS warning:
arch/arm64/boot/dts/freescale/imx8mn-tqma8mqnl-mba8mx-usbotg.dtb: sel-usb-hub-hog:
   {'output-low': True, 'gpio-hog': True, 'gpios': [[1, 0]], 'output-high': True, 'phandle': 108, '$nodename': ['sel-usb-hub-hog']}
       is valid under each of {'required': ['output-low']}, {'required': ['output-high']
