[PATCH v2] ARM: dts: exynos4210-trats: add max8997 IRQ

[Robert Baldyga]

This patch adds IRQ line specification for the MAX8997 chip and necessary
pinctrl group to configure pull-up and driver strength of the pin.
It's needed for proper handling of IRQs coming from MAX8997 multifunction
device (IRQs are used by PMIC, MUIC and RTC).
