hw/s390x/css-bridge: switch virtual-css bus to 3-phase-reset

Browse Source 
Switch the s390x virtual-css bus 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.
