'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

DT unit addresses should be lower case hex. Fix all the
binding examples.
Converted with the following command from Krzysztof Kozlowski:
sed -e 's/@\([a-fA-F0-9_-]*\) {/@\L\1 {/' -i $(find Documentation/devicetree/bindings -name '*.txt')

This patch adds support for v5 of SYSMMU controller, found in Samsung
Exynos 5433 SoCs. The main difference of v5 is support for 36-bit physical
address space and some changes in register layout and core clocks hanging.
This patch also adds support for ARM64 architecture, which is used by
Exynos 5433 SoCs.

Exynos SoC Device Tree bindings are spread over arm/exynos/ and
arm/samsung/ directories. There is no need for that separation and it
actually confuses. Put power domain bindings under power/ and
remaining samsung-boards.txt under arm/samsung/.

The current dt binding for Exynos System MMU can be changed, if found
incompatible with the support for "Generic IOMMU Binding".
This patch adds a note to the binding documentation stating the same.
