[PATCH v2 0/3] regulator: qcom_smd-regulator: fix PM2250 supply parent mappings

[Rakesh Kota]

The rpm_pm2250_regulators table hardcodes supply parent name strings
in the regulator descriptor, causing the Linux regulator framework to
vote on parent supplies from APPS unnecessarily. On RPM-based platforms,
parent-child supply relationships are managed entirely by RPM firmware.

Fix this by setting supply names to NULL in the driver descriptor, and
correct the supply parent mappings in the qrb2210 and Shikra DTS files
to match the actual PM4125 pin connections.
