[PATCH v2 4/3] mvebu: armada-370-xp: simplify soc init code flow

[Uwe Kleine-König]

This gets rid of a of-fixup which is strange because the soc init stuff
is rerun then when a new dt for booting into Linux is loaded.

The initcall must be postponed to post-core to ensure
of_machine_is_compatible is working correctly.

The call to mvebu_mbus_add_range is moved to drivers/bus/mvebu-mbus.c to
ensure it's registered early enough.
