leds: move LED trigger drivers into new subdirectory

For better driver management, new subdirectory, 'trigger' is created.
All LED trigger drivers are moved into this directory.

Internal header, 'leds.h' is included in each LED trigger drivers.
Fix the location of header file, "leds.h" -> "../leds.h" in driver files.
One exception is here, 'ledtrig-timer.c'.
There is no need to include 'leds.h'. so '#include "leds.h"' line was removed.

 	  This option enables support for the BlinkM RGB LED connected
 	  through I2C. Say Y to enable support for the BlinkM LED.
 
-config LEDS_TRIGGERS
-	bool "LED Trigger support"
-	depends on LEDS_CLASS
-	help
-	  This option enables trigger support for the leds class.
-	  These triggers allow kernel events to drive the LEDs and can
-	  be configured via sysfs. If unsure, say Y.
-
 comment "LED Triggers"
-
-config LEDS_TRIGGER_TIMER
-	tristate "LED Timer Trigger"
-	depends on LEDS_TRIGGERS
-	help
-	  This allows LEDs to be controlled by a programmable timer
-	  via sysfs. Some LED hardware can be programmed to start
-	  blinking the LED without any further software interaction.
-	  For more details read Documentation/leds/leds-class.txt.
-
-	  If unsure, say Y.
-
-config LEDS_TRIGGER_ONESHOT
-	tristate "LED One-shot Trigger"
-	depends on LEDS_TRIGGERS
-	help
-	  This allows LEDs to blink in one-shot pulses with parameters
-	  controlled via sysfs.  It's useful to notify the user on
-	  sporadic events, when there are no clear begin and end trap points,
-	  or on dense events, where this blinks the LED at constant rate if
-	  rearmed continuously.
-
-	  It also shows how to use the led_blink_set_oneshot() function.
-
-	  If unsure, say Y.
-
-config LEDS_TRIGGER_IDE_DISK
-	bool "LED IDE Disk Trigger"
-	depends on IDE_GD_ATA
-	depends on LEDS_TRIGGERS
-	help
-	  This allows LEDs to be controlled by IDE disk activity.
-	  If unsure, say Y.
-
-config LEDS_TRIGGER_HEARTBEAT
-	tristate "LED Heartbeat Trigger"
-	depends on LEDS_TRIGGERS
-	help
-	  This allows LEDs to be controlled by a CPU load average.
-	  The flash frequency is a hyperbolic function of the 1-minute
-	  load average.
-	  If unsure, say Y.
-
-config LEDS_TRIGGER_BACKLIGHT
-	tristate "LED backlight Trigger"
-	depends on LEDS_TRIGGERS
-	help
-	  This allows LEDs to be controlled as a backlight device: they
-	  turn off and on when the display is blanked and unblanked.
-
-	  If unsure, say N.
-
-config LEDS_TRIGGER_CPU
-	bool "LED CPU Trigger"
-	depends on LEDS_TRIGGERS
-	help
-	  This allows LEDs to be controlled by active CPUs. This shows
-	  the active CPUs across an array of LEDs so you can see which
-	  CPUs are active on the system at any given moment.
-
-	  If unsure, say N.
-
-config LEDS_TRIGGER_GPIO
-	tristate "LED GPIO Trigger"
-	depends on LEDS_TRIGGERS
-	depends on GPIOLIB
-	help
-	  This allows LEDs to be controlled by gpio events. It's good
-	  when using gpios as switches and triggering the needed LEDs
-	  from there. One use case is n810's keypad LEDs that could
-	  be triggered by this trigger when user slides up to show
-	  keypad.
-
-	  If unsure, say N.
-
-config LEDS_TRIGGER_DEFAULT_ON
-	tristate "LED Default ON Trigger"
-	depends on LEDS_TRIGGERS
-	help
-	  This allows LEDs to be initialised in the ON state.
-	  If unsure, say Y.
-
-comment "iptables trigger is under Netfilter config (LED target)"
-	depends on LEDS_TRIGGERS
-
-config LEDS_TRIGGER_TRANSIENT
-	tristate "LED Transient Trigger"
-	depends on LEDS_TRIGGERS
-	help
-	  This allows one time activation of a transient state on
-	  GPIO/PWM based hardware.
-	  If unsure, say Y.
