PCI: Add MSI masking quirk for Nvidia ION AHCI
stable inclusion from stable-5.10.81 commit 5bf5f464831c26dca627bf32d4e51067dcd39d64 bugzilla: 185832 https://gitee.com/openeuler/kernel/issues/I4L9CF Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=5bf5f464831c26dca627bf32d4e51067dcd39d64 -------------------------------- commit f21082fb upstream. The ION AHCI device pretends that MSI masking isn't a thing, while it actually implements it and needs MSIs to be unmasked to work. Add a quirk to that effect.
