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

Browse Source 
[ Upstream commit 8a45f33bd3 ]

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.
