[PATCH 06/10] MACH/Samsung/Mini2440: use leds-gpio driver for board leds

[Juergen Beisert]

From: Marek Belisko <marek.belisko at open-nandra.com>

Intention of this patch is convert existing usage of leds-s3c24xx driver
to use generic gpio-leds driver. Leds are separated to 2 devices.
First device handle 4 available leds. Second device is used to drive
LCD backlight. Backlight can be controlled via parameter b so we need
separate device which is registered or not depending on parameter.
