mfd: syscon: Add Atmel GPBR DT bindings documention
The GPBR block provides a set of battery-backed registers that can be used
to save data which need to be kept when the system is powered down and
VDD-core is maintained by an external battery.
A typical usage is the RTT block (when used as an RTC) which needs one of
those registers to save the current time.
