Subject: 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...]
