hwmon: add Corsair Commander Pro driver

This is v7 of a driver for the Corsair Commander Pro.
It provides sysfs attributes for:
- Reading fan speed
- Reading temp sensors
- Reading voltage values
- Writing pwm and reading last written pwm
- Reading fan and temp connection status

It is an usb driver, so it needs to be ignored by usbhid.
The Corsair Commander Pro is a fan controller and provides
no means for user interaction.
The two device numbers are there, because there is a slightly
different version of the same device. (Only difference
seem to be in some presets.)

Squashed:
 hwmon: (corsair-cpro) add fan_target

 This adds fan_target entries to the corsair-cpro driver.
 Reading the attribute from the device does not seem possible, so
 it returns the last set value (same as pwm).

 send_usb_cmd now has one more argument, which is needed for the
 fan_target command.

 hwmon: corsair-cpro: Change to HID driver

 This changes corsair-cpro to a hid driver using hid reports.

Kernel driver corsair-cpro
==========================
Supported devices:
* Corsair Commander Pro
* Corsair Commander Pro (1000D)
Author: Marius Zachmann
Description
-----------
This driver implements the sysfs interface for the Corsair Commander Pro.
The Corsair Commander Pro is a USB device with 6 fan connectors,
4 temperature sensor connectors and 2 Corsair LED connectors.
It can read the voltage levels on the SATA power connector.
Usage Notes
-----------
Since it is a USB device, hotswapping is possible. The device is autodetected.
Sysfs entries
-------------
======================= =====================================================================
in0_input Voltage on SATA 12v
in1_input Voltage on SATA 5v
in2_input Voltage on SATA 3.3v
temp[1-4]_input Temperature on connected temperature sensors
fan[1-6]_input Connected fan rpm.
fan[1-6]_label Shows fan type as detected by the device.
fan[1-6]_target Sets fan speed target rpm.
When reading, it reports the last value if it was set by the driver.
Otherwise returns 0.
pwm[1-6] Sets the fan speed. Values from 0-255.
When reading, it reports the last value if it was set by the driver.
Otherwise returns 0.

If you say yes here you get support for the Corsair Commander Pro
controller.
This driver can also be built as a module. If so, the module
will be called corsair-cpro.
