hwmon: pmbus: Add Inspur Power System power supply driver
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 <wangzqbj@inspur.com>
+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
+Sysfs entries
+The following attributes are supported:

+curr1_input Measured input current
+curr1_label "iin"
+curr1_max Maximum current
+curr1_max_alarm Current high alarm
+curr2_input Measured output current in mA.
+curr2_label "iout1"
+curr2_crit Critical maximum current
+curr2_crit_alarm Current critical high alarm
