HID: thingm: refactor blink(1) support
This patch refactors the way the thingm driver registers a blink(1) LED. In order to make the driver simpler and more standard, drop the "rgb" sysfs attribute and create one instance of LED class per RGB channel. Actually, the name of the LED class instance registered for a blink(1) device is "blink1::ABCD", where ABCD is the last 4 chars of the serial number. The driver now registers 3 instances per RGB chip, named "thingmX:{red,green,blue}:ledY" where X is the hidraw minor number and Y is the RGB chip number (as seen by the firmware). This patch also uses work queues to defer calls with the device, which now allows triggers to work as expected with this LED device. Also remove the brightness structure field and the brightness_get backend, as it is already handled by the LED class, and changes the prefix of functions and structures to thingm_ to match the driver name.
