ARM: dts: exynos: correct fuel gauge interrupt trigger level on Midas family

[ Upstream commit 8a45f33bd36efbb624198cfa9fdf1f66fd1c3d26 ]

The Maxim fuel gauge 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.
