In order to be able to populate the device msi_domain field,
add the necessary hooks to propagate the host bridge msi_domain
across secondary busses to devices.
So far, nobody populates the initial msi_domain.

Nit: there isn't a pcibios callback anymore.
There is actually one, in pci_add_device:
[...]
ret = pcibios_add_device(dev);
WARN_ON(ret < 0);
/* Setup MSI irq domain */
pci_set_msi_domain(dev);
[...]
pcibios_add_device is the one I was referring to. I'll clarify the comment.
Oh, right! I thought you were referring to
pcibios_set_host_bridge_msi_domain(), which got removed, but of course
that wouldn't even make sense.
