PCI: use config space encoding in pci_get_interrupt_pin()
This patch makes pci_get_interrupt_pin() return values encoded the same way as the "Interrupt Pin" value in PCI config space, i.e., 1=INTA, ..., 4=INTD. pirq_bios_set() is the only in-tree caller of pci_get_interrupt_pin() and pci_get_interrupt_pin() is not exported.
