3.16.63-rc1 review patch. If anyone has any objections, please let me know.

From: Marek Szyprowski m.szyprowski@samsung.com
commit f5e758b8358f6c27e8a351ddf0b441a64cdabb94 upstream.
PMIC_IRQB and PMIC_KEYINB lines on Exynos4210-based Origen board have external pull-up resistors, so disable any pull control for those lines in respective pin controller node. This fixes support for MAX8997 interrupts and enables operation of wakeup from MAX8997 RTC alarm.
