arm64: dts: exynos: correct PMIC interrupt trigger level on TM2

Browse Source 
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.

Fixes: 01e5d23521 ("arm64: dts: exynos: Add dts file for Exynos5433-based TM2 board")
