I thought we already select 'MIGHT_HAVE_PCI' and 'PCI_DOMAINS' for
all ARMv7 platforms. If not, we probably should.

For PCI_MSI, I would leave that as user-selectable, there is no
need to enforce that as far as I can tell. If the driver needs
PCI_MSI support at compile-time, a dependency for that driver
would make sense.
