swap led_brightness from enum to typedef

This commit changes how led_brightness, declared in header file
include/linux/leds.h, works throughout the kernel, and updates other
files in accordance.

The TODO located at drivers/leds/TODO requests:

* Get rid of led_brightness

It is really an integer, as maximum is configurable. Get rid of it, or
make it into typedef or something.

This patch changes the declaration of led_brightness from an enum to a
typedef. In order to hold the currently existing enum values, macro
definitions are provided. Files which use led_brightness are updated to
conform to the new types.
