ARM: dts: exynos: correct MUIC interrupt trigger level on Midas family
The Maxim MUIC 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.
Additionally, the interrupt line is shared so using level sensitive
interrupt is here especially important to avoid races.
