[PATCH 2/8] hw/pci-host/designware: Initialize root function in host bridge realize

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

There are no root function properties exposed by the host
bridge, so using a 2-step QOM creation isn't really useful.

Simplify by creating the root function when the host bridge
is realized.
