[Qemu-devel] [PATCH 26/27] pc: create separate init function for pc-1.3

[Eduardo Habkost <ehabkost@redhat.com>]

This:
 - Renames the init function for pc-1.2 and lower to pc_init_pci_v1_2;
 - Creates a pc_init_pci_v1_3 function for pc-1.3.

Right now both functions have exactly the same code, but the following patch
will change pc_init_v1_2 to set compatibility PCInitArgs fields.

Cc: "Michael S. Tsirkin" <mst@redhat.com>

This patch conflicts with a patch from Michael S. Tsirkin. If his patch
gets into the tree first (which is likely), I can rebase this one to use
the new function created by Michael.
