Subject: [PATCH v1] arm64: dts: freescale: imx8mm-verdin: enable hysteresis on slow input pin

From: Max Krummenacher <[email protected]>

SODIMM 17 can be used as an edge triggered interrupt supplied from an
off board source.

Enable hysteresis on the pinmuxing to increase immunity against noise
on the signal.

Fixes: 60f01b5b5c7d ("arm64: dts: imx8mm-verdin: update iomux configuration")
