led: add blinking/flashing and led_blink_pattern interface
So far blinking/flashing LEDs is only supported on led-trigger level.
Even without triggers it useful to be able to blink/flash LEDs, so
add this functionality to the LED core.
A led_blink_pattern consists of a number of on and off-periods which
are described in an array. Using such an array you can encode nearly
every blink pattern you need.
