From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
[ Upstream commit 98f7b86a0becc1154b1a6df6e75c9695dfd87e0d ]
People reported that old Apple machines are not working properly if the non-first IRQ vector is in use.
Set quirk for that models to limit IRQ to use first vector only.
Based on original patch by GitHub user npx001.
