[PATCH 2/5] vmbus: Switch bus reset to 3-phase-reset

[Peter Maydell]

Switch vmbus from using BusClass::reset to the Resettable interface.

This has no behavioural change, because the BusClass code to support
subclasses that use the legacy BusClass::reset will call that method
in the hold phase of 3-phase reset.
