dt-bindings: reset: Add TPS380x documentation 



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.
