PCI/MSI: Check the device specific address mask in msi_verify_entries()
Instead of a 32-bit/64-bit dichotomy, check the MSI address against
the device specific address mask.
This allows platforms with an MSI doorbell address above the 32-bit limit
to work with devices without full 64-bit MSI address support, as long as
the doorbell is within the addressable range of the device.
