s390/pci: externalize the SIC operation controls and routine
A subsequent patch will be issuing SIC from KVM -- export the necessary
routine and make the operation control definitions available from a header.
Because the routine will now be exported, let's rename __zpci_set_irq_ctrl
to zpci_set_irq_ctrl and get rid of the zero'd iib wrapper function of
the same name.
