[PATCH 11/16] ARM: mvebu: dts: Add CA9 MPcore SoC Controller node

[Gregory CLEMENT <gregory.clement@free-electrons.com>]

The CA9 MPcore SoC Control block allows to do some configuration that
the SoC could use for a specific use case. In most cases the defaults
case is enough. However there is few exception: for cpuidle we need to
use the CA9 MPcore Reset Control register.

The documentation is also updated in the same time.
