[PATCH 3/3] arm64: dts: qcom: shikra: add vph_pwr and fix supply parent mappings

[Rakesh Kota]

Add the vph_pwr fixed regulator representing the PM4125 charger output
supplied by VBAT, and add the correct per-group supply properties
matching the actual PM4125 pin connections on Shikra. Also add the
pm4125_s1 and pm4125_s4 regulator nodes.
