Implement hack to enable audio thru docks on Motorola phones

This allows us to pass a routing parameter to io 1 while sending
the DockState parameter to io 0 simultaneously. This is required
to enable the correct audio routing when docking/undocking and
allows audio on docks to work when combined with the DockAudio
package.
