Subject: [PATCH v2] arm: dts: artpec6: Remove unnecessary interrupt-parent property from sub-nodes

From: Surender Polsani <surenderp@...hveda.org>

"interrupt-parent" property is declared in root node, so it is global
to all nodes. This property is re-declared in few sub-nodes. To avoid
duplication this property is removed from following sub-nodes: pmu,
amba@0, amba@...thernet.
