[PATCH] hwmon: (pmbus/xdpe1a2g7b) Add regulator support

[Abdurrahman Hussain]

Register both dual-loop output channels with the regulator framework by
populating regulator_desc[] and num_regulators in pmbus_driver_info.
This exposes the standard PMBus OPERATION-based on/off control and
status reporting to consumer drivers.

The new SENSORS_XDPE1A2G7B_REGULATOR Kconfig and the ifdef-guarded
regulator_desc array mirror the opt-in pattern already used by the
XDPE122 driver (SENSORS_XDPE122_REGULATOR), so the REGULATOR dependency
stays optional for users that only need hwmon monitoring.
