The defer reset object is to send board specific reset signal and this signal has to be sent after some device is intialized. For example, a USB device may need extra reset signal after root hub is initialized. As machine init code is run before driver init-call, can not add reset sending here if it depends on a specific device's initialization. Also it provides a DT node that helps both HW/SW developer to use this feature.
