[PATCH 12/18] ARM: dts: qcom: msm8974-samsung-klte: correct fuel gauge interrupt trigger level
From: Krzysztof Kozlowski <krzk@kernel.org>

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.
