[PATCH v3 2/7] pci/msi: Add device flag indicating that 64-bit MSIs don't work

This can be set by quirks/drivers to be used by the architecture code that assigns the MSI addresses. We additionally add verification in the core MSI code that the values assigned by the architecture do satisfy the limitation in order to fail gracefully if they don't (ie. the arch hasn't been upd
