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

We need to be able to use OHCISysBusState outside hcd-ohci.c, so move it
to its include file.

We'll use this property in a follow-up patch to insantiate an EHCI
bus with companion support.

Instantiate EHCI and OHCI controllers on Allwinner A10. OHCI ports are
modeled as companions of the respective EHCI ports.

With this patch applied, USB controllers are discovered and instantiated
when booting the cubieboard machine with a recent Linux kernel.

Hi; I tried to apply this patchset, but it doesn't apply to master.
In particular, master doesn't have a #define for AW_A10_CCM_REG_BASE.

Is this patchset supposed to be based on some other patchset
you've already sent that's got lost in my mailbox?

thanks

It is not supposed to be based on anything, but in practice it is because
I also carry a patch adding basic CCM support (which I completely forgot
and which I didn't send upstream because it is hackish).

Sorry for that. I'll rebase to master and resend.
