[PATCH 0/3] add vdda-aux regulator support for QMP PHY on QCS6490

[Amit Singh]

The `vdda-aux` supply is necessary for proper power sequencing and reliable
USB enumeration on platforms that provide this rail.

This series adds support for the `vdda-aux` regulator to the QMP PHY driver
and updates the QCS6490 RB3 Gen2 device tree to provide the required
auxiliary 3.0 V rail for stable USB PHY operation.
Platforms that do not define `vdda-aux` remain unaffected.

Tested on RB3 Gen2 (QCS6490) platform to ensure proper USB enumeration and
PHY stability.
