The legacy function qdev_reset_all() performs a recursive reset,
starting from a qdev. However, it does not permit any of the devices
in the tree to use three-phase reset, because device reset goes
through the device_legacy_reset() function that only calls the single
DeviceClass::reset method.
Switch to using the device_cold_reset() function instead. This also
performs a recursive reset, where first the children are reset and
then finally the parent, but it uses the new (...in 2020...)
Resettable mechanism, which supports both the old style single-reset
method and also the new 3-phase reset handling.
This commit changes the five remaining uses of this function.
