Add device-tree binding documentation for the tps380x reset driver. The
binding uses enum to make it easy to add more devices from that family.

+description: |
+ The TPS380x family [1] of supervisory circuits monitor supply voltages to
+ provide circuit initialization and timing supervision. The devices assert a
+ RESET signal if the voltage drops below a preset threshold or upon a manual
+ reset input (MR). The RESET output remains asserted for the factory
+ programmed delay after the voltage return above its threshold or after the
+ manual reset input is released.
