Subject: [RFT v3 5/8] ARM: dts: exynos: Remove MCT subnode for interrupt map on Exynos4412

Multi Core Timer node has interrupts routed to two different parents -
GIC and combiner.  This was modeled with a interrupt-map within a
subnode but can be expressed in an easier and more common way, directly
in the node itself.

Tested on Odroid U3 (Exynos4412).
