Instantiate EHCI and OHCI controllers on Allwinner A10.

The first patch in the series moves the declaration of EHCISysBusState
from hcd-ohci.c to hcd-ohci.h. This lets us add the structure to
AwA10State. Similar, TYPE_SYSBUS_OHCI is moved to be able to use it
outside its driver.

The second patch introduces the ehci-sysbus property "companion-enable".
This lets us use object_property_set_bool() to enable companion mode.

The third patch instantiates EHCI and OHCI ports for Allwinner-A10
and marks the OHCI ports as companions of the respective EHCI ports.

Tested by attaching various high speed and full speed devices, and by
booting from USB drive.

v2: Add summary
    Rewrite to instantiate OHCI in companion mode; add patch 2/3
    Merge EHCI and OHCI instantiation into a single patch
