arm64: dts: freescale: imx8mm-verdin: enable hysteresis on slow input pin

[ Upstream commit 67cc6125fb39902169707cb6277f010e56d4a40a ]

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.
