This RTC device has a POR submodule, which is explained in the description.
The corresponding driver of the POR submodule provides power off
restart function.
The driver of the POR submodule just uses reg to work.As you mentioned in your
last comment.POR  is empty, so there is little point in having it as
subnode. we need
share the reg to POR. RTC driver and POR driver will access this
address simultaneously.
so,I added this syscon attribute.
