mb/hp/z220_series: Add missing PCI Interrupt Routing Table
HP Z220 series has PCI slot(s) but Interrupt Routing Table in ACPI
used to be missing, so one is added.
Note that the values within the added one are obtained from my own SFF
variant. If other variants have different values, please add them in a
manner similar to mb/gigabyte/ga-b75m-d3h/acpi/pci.asl.
Test result:
Log lines like
pci 0000:00:1e.0: can't derive routing for PCI INT A
ath9k 0000:04:00.0: PCI INT A: no GSI
disappeared from dmesg.
