Commit Message

Peter Maydell Feb. 2, 2024, 3:36 p.m. UTC 
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.
