HID: add ThingM blink(1) USB RGB LED support 

The ThingM blink(1) is an open source hardware USB RGB LED. It contains
an internal EEPROM, allowing to configure up to 12 light patterns. A
light pattern is a RGB color plus a fade time. This driver registers a
LED class instance with additional sysfs attributes to support basic
functions such as setting RGB colors, fade and playing. Other functions
are still accessible through the hidraw interface.

At this time, the only documentation for the device is the firmware
source code from ThingM, plus a few schematics. They are available at:

https://github.com/todbot/blink1



This patch is version 3. It updates the name of the source file, the
driver and the led sysfs entry, according to comments from Jiri Kosina
and Simon Wood.

Description:	The ThingM blink1 is an USB RGB LED. The color notation is

		3-byte hexadecimal. Read this attribute to get the last set

		color. Write the 24-bit hexadecimal color to change the current

		LED color. The default color is full white (0xFFFFFF).

		For instance, set the color to green with: echo 00FF00 > rgb

Description:	This attribute allows to set a fade time in milliseconds for

		the next color change. Read the attribute to know the current

		fade time. The default value is set to 0 (no fade time). For

		instance, set a fade time of 2 seconds with: echo 2000 > fade



What:		/sys/class/leds/blink1::<serial>/play

Date:		January 2013

Contact:	Vivien Didelot <vivien.didelot@savoirfairelinux.com>

Description:	This attribute is used to play/pause the light patterns. Write 1

		to start playing, 0 to stop. Reading this attribute returns the

		current playing status.
