ARM: dts: exynos: correct PMIC interrupt trigger level on Odroid XU3 family
[ Upstream commit 3e7d9a583a24f7582c6bc29a0d4d624feedbc2f9 ]
The Samsung PMIC datasheets describe the interrupt line as active low
with a requirement of acknowledge from the CPU. The falling edge
interrupt will mostly work but it's not correct.
