Samsung YP-R0 LCD improvements
This patch adds to YP-R0 (and other future targets using Linux
framebuffer) the ability to use LCD_ENABLE to save some CPU cycles
while display is powered off.
This patch also changes the way to toggle LCD power: now using
a proper ioctl call, slightly more efficient.
