[PATCH v1 1/1] arm64: dts: imx8mm-var-som: fix touchscreen IRQ trigger

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r@xxxxxxxxxxxxx>

The touchscreen interrupt is configured as level-high, causing a
pending wakeup that prevents Symphony from entering suspend.

Change the interrupt to falling-edge so the board can suspend
with touchscreen wakeup enabled.
