intel/bd82x6x: Use generated ACPI PIRQ
Enable change Ic6b8ce4a9db50211a9c26221ca10105c5a0829a0
(sb/intel/common: Automatically generate ACPI PIRQ) for BD82X6X.
This generates the main ACPI _PRT table automatically based on the
chipset registers.
Tested on Intel NUC DCP847SKE with Linux 4.13.14:
$ cat /proc/interrupts
CPU0 CPU1
0: 23 0 IO-APIC 2-edge timer
8: 1 0 IO-APIC 8-edge rtc0
9: 0 0 IO-APIC 9-fasteoi acpi
19: 86 0 IO-APIC 19-fasteoi ehci_hcd:usb1
23: 0 0 IO-APIC 23-fasteoi i801_smbus
[...MSI and other interrupts skipped...]
