[PATCH v3 8/8] PCI: add QCN9274 to reset quirks and KVM MSI domain

[Jose Ignacio Tornos Martinez]

In order to have Qualcomm QCN9274 (PCI ID 17cb:1109) completely
operational from VM environments, add to:

1. quirk_no_bus_reset: Disable broken bus reset, as with WCN6855 and
   WCN7850.

2. pci_dev_specific_reset_methods: Use the existing
   reset_qualcomm_wlan function. Unlike WCN7850, the QCN9274 is not
   initialized at all without a valid device-specific reset method.

3. kvm_msi_devids in pci-kvm-msi: Enable KVM MSI domain support for
   VFIO passthrough to VMs.
