genirq/msi: Provide constants for PCI/IMS support
Provide the necessary constants for PCI/IMS support:
- A new bus token for MSI irqdomain identification
- A MSI feature flag for the MSI irqdomains to signal support
- A secondary domain id
The latter expands the device internal domain pointer storage array from 1
to 2 entries. That extra pointer is mostly unused today, but the
alternative solutions would not be free either and would introduce more
complexity all over the place. Trade the 8bytes for simplicity.
