Subject: [PATCH v4 7/8] ARM: dts: exynos: Remove MCT subnode for interrupt map on Exynos54xx

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 XU (Exynos5410), Odroid HC1 (Exynos5422) and Arndale
Octa (Exynos5420).

Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>

Changes since v3:
1. Use interrupts-extended instead of interrupts-map.
