[PATCH v2] xen/pci: Use acpi_noirq_set() helper

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

No need to keep an #ifdef since we have a helper (in x86 world).
Use it instead.

- resend as v2 with slightly longer Cc list, i.e. +Rafael and ACPI ML
- in v1 Bjorn told he is okay with patch, but assumed it goes not via PCI tree
