[PATCH 3/3] PCI: altera: fix error when INTX is 4

[Ley Foon Tan]

PCI interrupt lines start at 1, not at 0. So, change INTX_NUM to 5.

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.
