[PATCH 2/3] phy: qcom: qmp-combo: add vdda-aux regulator

Add "vdda-aux" to the QMP PHY regulator list with an enable_load of
36000 µA, allowing the driver to manage the auxiliary supply when
present in device trees.

This aligns power sequencing with existing "vdda-phy" and
"vdda-pll" rails, and is required for platforms that depend on
the auxiliary 3.0 V rail for stable QMP operation. Platforms that
do not define "vdda-aux" remain unaffected.
