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.

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.
