dt-bindings: rtc: mpfs-rtc: permit resets

Browse Source 
The RTC on mpfs and pic64gx has a reset pin, but until now this has been
undocumented because platform firmware takes the RTC out of reset on
first-party boards (or those using modified versions of the vendor
firmware), but not all boards may take this approach. Permit providing a
reset in devicetree for Linux, or other devicetree-consuming software,
to use.
