arm64: dts: exynos: correct PMIC interrupt trigger level on TM2
[ Upstream commit e98e2367dfb4b6d7a80c8ce795c644124eff5f36 ]
The Samsung PMIC datasheets describe the interrupt line as active low
with a requirement of acknowledge from the CPU. Without specifying the
interrupt type in Devicetree, kernel might apply some fixed
configuration, not necessarily working for this hardware.
