hwmon: (pmbus/xdpe1a2g7b) Add regulator support

Browse Source 
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.

This driver can also be built as a module. If so, the module will
be called xdpe1a2g7b.

If you say yes here you get regulator support for Infineon
XDPE1A2G5B and XDPE1A2G7B multi-phase digital controllers.
This enables the controllers to be used as regulator devices,
providing voltage control through the regulator framework.
