[Qemu-devel] [PATCH 04/10] spapr_vio: Introduce a liobn number generating macros

[Alexey Kardashevskiy <aik@ozlabs.ru>]

This introduces a macro which makes up a LIOBN from fixed prefix and
VIO device address (@reg property).

This is to keep LIOBN macros rendering consistent - the same macro for
PCI has been added by the previous patch.
