This driver uses PCI glue that is only available on 32-bit ARM. This
used to work fine as long as ARCH_MVEBU and ARCH_DOVE were exclusively
32-bit, but that's changed now, with ARCH_MVEBU also being available
on 64-bit ARM.

Looks fine as a temporary workaround, but I think what we really want to
do here is to remove the dependency, as the new ARM64 platforms are going
to need this driver anyway.

Actually the mvebu ARM64 platform we know about (Armada 3700, 7K and
8K), won't use the same controller. A7K/A8K will use a synopsis IP and
Armada 3700 a new Marvell IP.

So for me depending on ARM32 is enough.
