hwmon: pmbus: Add Inspur Power System power supply driver

Browse source 
Add the driver to monitor Inspur Power System power supplies
with hwmon over pmbus.

This driver adds sysfs attributes for additional power supply data,
including vendor, model, part_number, serial number,
firmware revision, hardware revision, and psu mode(active/standby).

Kernel driver inspur-ipsps1
=======================
Supported chips:
* Inspur Power System power supply unit
Author: John Wang <[email protected]>
Description
-----------
This driver supports Inspur Power System power supplies. This driver
is a client to the core PMBus driver.
Usage Notes
-----------
This driver does not auto-detect devices. You will have to instantiate the
devices explicitly. Please see Documentation/i2c/instantiating-devices for
details.
