ARM: dts: exynos: Add missing PMIC interrupts on UniversalC210 board
PMIC node requires external interrupts for proper operation. Lack of them was probably caused by a limited support for interrupts from more than one parent, which was not possible to define when support for this board was added. Fix this by adding 'interrupt-extended' property and properly define both interrupt lines for PMIC node.
