HID: roccat: Add support for Roccat Arvo keyboard

Browse source 
This patch add support for Roccat Arvo keyboard. Arvo has 5 additional
configurable buttons and the ability to deactivate certain keys.
Userland tools can soon be found at http://sourceforge.net/projects/roccat

What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/arvo/roccatarvo<minor>/actual_profile
Date: Januar 2011
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The integer value of this attribute ranges from 1-5.
When read, this attribute returns the number of the actual
profile which is also the profile that's active on device startup.
When written this attribute activates the selected profile
immediately.

Date: Januar 2011
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The keyboard can store short macros with consist of 1 button with
several modifier keys internally.
When written, this file lets one set the sequence for a specific
button for a specific profile. Button and profile numbers are
included in written data. The data has to be 24 bytes long.
This file is writeonly.

Date: Januar 2011
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: When read, this file returns some info about the device like the
installed firmware version.
The size of the data is 8 bytes in size.
This file is readonly.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/arvo/roccatarvo<minor>/key_mask
Date: Januar 2011
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The keyboard lets the user deactivate 5 certain keys like the
windows and application keys, to protect the user from the outcome
of accidentally pressing them.
The integer value of this attribute has bits 0-4 set depending
on the state of the corresponding key.
When read, this file returns the current state of the buttons.
When written, the given buttons are activated/deactivated
immediately.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/arvo/roccatarvo<minor>/mode_key
Date: Januar 2011
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The keyboard has a condensed layout without num-lock key.
Instead it uses a mode-key which activates a gaming mode where
the assignment of the number block changes.
The integer value of this attribute ranges from 0 (OFF) to 1 (ON).
When read, this file returns the actual state of the key.
When written, the key is activated/deactivated immediately.
