Thanks for your information. 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.

Best regards,
Houcheng Lin
