[PATCH] ARM: mvebu: Add a ranges entry to translate devbus childs

From: Ezequiel Garcia <ezequiel.garcia at free-electrons.com>

With the latest device tree reorganization which introduced the
'internal-reg' node, now the only region translated is the internal register's.
This makes the description of the hardware incomplete, for it lacks the
Device Bus childs address space.

In order to fix this, it's required to add a 'ranges' entry with a suitable
address space to map Device Bus childs, on a per-board basis.

Signed-off-by: Ezequiel Garcia <ezequiel.garcia at free-electrons.com>
Applies on v3.10-rc1. This is meant for v3.10.
