Convert ledtrig-ide-disk code to use the generic API for one-shot LED
blinking.
This patch changes slightly the behaviour of the trigger, as while the
original version kept the LED on under heavy activity, the new one keeps
a constant on-off blink at 1 / (2 * BLINK_DELAY) Hz.
(bryan.wu@canonical.com: remove 2 useless included header files)

This patch allows drivers to override the default maximum brightness value
of 255. We take care to preserve backwards-compatibility as much as
possible, so that user-space ABI doesn't change for existing drivers.
LED trigger code has also been updated to use the per-LED maximum.

Break the lines which were more than 80 characters into more
lines; replace SPACEs with TABs; correct ident at switch-case;
change character encoding from ISO-8859-2 to UTF-8.
The order of the functions in led-triggers.c changed in order
the similar functions can still be together under titles
"Used by LED Class", "LED Trigger Interface" and "Simple
LED Tigger Interface" as was grouped before when exported
with EXPORT_SYMBOL.
