 * Reset @bus and perform a bus-level ("hard") reset of all devices connected

 * to it, including recursive processing of all buses below @bus itself.  A

 * hard reset means that qbus_reset_all will reset all state of the device.

 * For PCI devices, for example, this will include the base address registers
