kvm: remove hard dependency on pci
The msi routing code in kvm calls some pci functions: provide
some stubs to enable builds without pci.
Also, to make this more obvious, guard them via a pci_available boolean
(which also can be reused in other places).
Fixes: e1d4fb2de ("kvm-irqchip: x86: add msi route notify fn")
Fixes: 767a554a0 ("kvm-all: Pass requester ID to MSI routing functions")
