PCI: altera: Fix error when INTx is 4
PCI interrupt lines start at 1, not at 0. So, creates additional one
interrupt when register for irq domain.
Error when PCIe devices have 4 INTx:
WARNING: CPU: 1 PID: 1 at kernel/irq/irqdomain.c:280
irq_domain_associate+0x17c/0x1cc()
error: hwirq 0x4 is too large for dummy
Tested on Ethernet adapter card with multi-functions.
