[ Upstream commit 62623718fd31d08b26ebea6c8b40f24924153ab7 ]
S2MPS14 PMIC interrupt line on Exynos3250-based Artik5 evaluation board
has external pull-up resistors, so disable any pull control for it in
controller node. This fixes support for S2MPS14 PMIC interrupts and
enables operation of wakeup from S2MPS14 RTC alarm.
