regulator: qcom_usb_vbus: add support for qcom,pm4125-vbus-reg

Browse source

The PM4125 PMIC uses a different register layout for USB VBUS control
compared to PM8150B. On PM4125, CMD_OTG is at offset 0x50, OTG_CFG is
at 0x56, and offset 0x52 is a 2-bit VBOOST voltage selector rather than
a current-limit selector.

Add pm4125_data using the abstraction introduced for PM8150B, along with
dedicated voltage-selector ops and the pm4125_vboost_table covering the
four supported boost voltages: 4.25 V, 4.5 V, 4.75 V, and 5.0 V.
