[PATCH 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. It also only calls
mvebu_mbus_add_range if we're running on an Armada 370 or XP and inlines
a simple function.

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