In the case a device can support retaining the firmware memory across low power states it is useful for the preloader widget to only power up whilst actually loading/unloading the core, as opposed to the normal operation where the widget is powered for the entire time a firmware is preloaded onto the core. Add support for this mode and a flag to enable it.
