x86/hyperv: Switch to msi_create_parent_irq_domain()
Move away from the legacy MSI domain setup, switch to use
msi_create_parent_irq_domain().
While doing the conversion, I noticed that hv_irq_compose_msi_msg() is
doing more than it is supposed to (composing message content). The
interrupt allocation bits should be moved into hv_msi_domain_alloc().
However, I have no hardware to test this change, therefore I leave a TODO
note.
