Revert "ARM: dts: exynos: Add missing interrupt-controller properties to Exynos5410 PMU"

This reverts commit 6737b081.

Unlike on Exynos5420-family, on Exynos5410 the PMU is not an interrupt
controller so it should not handle interrupts of RTC.  The DTC warning
(addressed by mentioned commit) should be fixed by not routing RTC
interrupts to PMU.
