s390x: always provide pci support
We tried to make pci support optional on s390x in the past;
unfortunately, we still require the s390 phb to be created
unconditionally due to backwards compatibility issues.
Instead of sinking more effort into this (including compat
handling for older machines etc.) for non-obvious gains, let's
just make CONFIG_PCI something that is always set on s390x.
Note that you can still fence off pci for the _guest_ if you
provide a cpu model without the zpci feature.
