ARM: dts: exynos: correct PMIC interrupt trigger level on Artik 5

Browse source 
[ Upstream commit cb31334687db31c691901269d65074a7ffaecb18 ]

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.
