regulator: qcom_usb_vbus: add register abstraction and PM8150B support

Introduce per-compatible regulator descriptor data via struct
qcom_usb_vbus_reg_data to abstract register layout differences between
PMICs. This allows the probe function to dynamically populate the
regulator_desc fields rather than relying on compile-time constants.

Refactor the existing PM8150B support to use this abstraction, wiring in
its CMD_OTG, OTG_CFG, and current-limit registers through pm8150b_data.
No functional change is intended for PM8150B.
