[PATCH 04/11] ARM: mvebu: convert Armada 370/XP devices to be probed from DT

[Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>]

With Armada 370/XP DT files available, convert Armada 370/XP SoC init
to register basic devices from DT only. Makefile targets for dtbs will
be removed again as soon as MULTI_PBL is available.
