leds: support automatic start of blinking with ledtrig-timer
By setting initial values blink_delay_on and blink_delay_off in a led_classdev struct, this change starts the blinking when the led is initialized. With this patch, you can initialize blink_delay_on and blink_delay_off in led_classdev with default_trigger set to "timer", and the led will start up blinking. The current ledtrig-timer implementation ignores any initial blink_delay_on/blink_delay_off settings, and requires setting blink_delay_on/blink_delay_off (typically from userspace) before the led blinks.
