ARM: dts: exynos: correct PMIC interrupt trigger level on Arndale Octa
[ Upstream commit 1ac8893c4fa3d4a34915dc5cdab568a39db5086c ]
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.
