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

Browse Source 
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.

Fixes: e8614292cd ("ARM: dts: Add Maxim 77693 fuel gauge node for exynos4412-trats2")
