3e80f6902c qdev: Convert uses of qdev_create() with Coccinelle 
This is the transformation explained in the commit before previous.
Takes care of just one pattern that needs conversion.  More to come in
this series.

The first rule exempts hw/arm/highbank.c, because it matches along two
control flow paths there, with different @type_name.  Covered by the
next commit's manual conversions.

Missing #include "qapi/error.h" added manually.

d9e8553bc8 hw/xtensa: add virt machine 
virt machine is a sim machine with generic PCI host controller.
Make common parts of sim machine initialization reusable.
Add PCI controller at 0xf0000000 with PIO space at its base address,
ECAM space at base address + 1M and MMIO space at base address + 64M.
Connect IRQ lines to consecutive CPU external IRQ pins starting from 0.
Instantiate network interfaces on virt machine.

Xtensa linux kernel configuration virt_defconfig can successfully boot
on this machine.
