since it doesn't harm even if a platform has a single PCIe port, it should be
okay to set PCI_DOMAINS. I'll resend the following as a separate patch if it's
okay.

Sounds good, but please remove all other 'select PCI_DOMAINS if PCI'
statements in arch/arm then in the same patch.

I have checked that all of them are for ARCH_MULTIPLATFORM based machines.
