ARM: dts: s5pv210: correct fuel gauge interrupt trigger level on Fascinate family

BugLink: https://bugs.launchpad.net/bugs/1929455
[ Upstream commit 214e6ec8c9f5a3353d3282b3ff475d3ee86cc21a ]

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.
