arm: mvebu: move cache and mvebu-mbus initialization later
Current, the L2 cache and the mvebu-mbus drivers are initialized at
->init_early() time. However, at ->init_early() time, ioremap() only
works if a static I/O mapping has already been put in place. If it's
not the case, it tries to do a memory allocation with kmalloc() which
is not possible so early at this stage of the initialization.
Since we want to get rid of the static I/O mapping, we cannot
initialize the L2 cache driver and the mvebu-mbus driver so early. So,
we move their initialization to the ->init_time() level, which is
slightly later (so ioremap() works properly), but sufficiently early
to be before the call of the ->smp_prepare_cpus() hook, which creates
an address decoding window for the BootROM, which requires the
mvebu-mbus driver to be properly initialized.
