[PATCH AUTOSEL 4.14 17/22] nvme-pci: Use single IRQ vector for old Apple models

[Sasha Levin <sashal@kernel.org>]

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.
