[PATCH v2 5/3] mvebu: dove: simplify soc init code flow

Similar to the previous commit, 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.
