regulator: dt-bindings: qcom,wcn3990-pmu: describe PMUs on WCN39xx 



WCN3990 and other similar WiFi/BT chips incorporate a simple on-chip PMU
(clearly described as such in the documentation). Provide DT schema
covering other Qualcomm WiFi/BT chips to cover these devices too.

description:

  The WCN3990 package contains discrete modules for WLAN and Bluetooth. They

  are powered by the Power Management Unit (PMU) that takes inputs from the

  host and provides LDO outputs. This document describes this module.
