hwmon: add Corsair PSU HID controller driver The Corsair digital power supplies of the series RMi, HXi and AXi include a small micro-controller with a lot of sensors attached. The sensors can be accessed by an USB connector from the outside. This micro-controller provides the data by a simple proprietary USB HID protocol. The data consist of temperatures, current and voltage levels, power usage, uptimes, fan speed and some more. It is also possible to configure the PSU (fan mode, mono/multi-rail, over current protection). This driver provides access to the sensors/statistics of the RMi and HXi series power supplies. It does not support configuring these devices, because there would be many ways to misconfigure or even damage the PSU.

Description
-----------
This driver implements the sysfs interface for the Corsair PSUs with a HID protocol
interface of the HXi and RMi series.
These power supplies provide access to a micro-controller with 2 attached
temperature sensors, 1 fan rpm sensor, 4 sensors for volt levels, 4 sensors for
power usage and 4 sensors for current levels and addtional non-sensor information
like uptimes.

Usage Notes
-----------
It is an USB HID device, so it is auto-detected and supports hot-swapping.
Flickering values in the rail voltage levels can be an indicator for a failing
PSU. The driver also provides some additional useful values via debugfs, which
do not fit into the hwmon class.
