ARM: 7080/1: l2x0: make sure I&D are not locked down on init
commit bac7e6ecf60933b68af910eb4c83a775a8b20b19 upstream.
Fighting unfixed U-Boots and other beasts that may the cache in
a locked-down state when starting the kernel, we make sure to
disable all cache lock-down when initializing the l2x0 so we
are in a known state.
