[Skyeye-developer] LCD simulation for device at91rm9200 device.

It's recommended to add new LCD controller simulation like below:
(for example, Epson S1D13506)

1. create your implementation:
(lookup-table dependable simulation according to "dev_lcd_s3c44b0x.c",
true-color simulation according to "dev_lcd_s3c2410.c")

device/lcd/dev_lcd_s1d13506.c
device/lcd/dev_lcd_s1d13506.h

2. add "lcd_*_init" function to "lcd_int" in "device/lcd/skyeye_lcd.c" like:
static void
lcd_init (struct device_module_set *mod_set)
{
	...
	...
	lcd_s1d13506_init (mod_set);
}

3. modify "Makefile" like:
SIM_LCD_OBJS =  ... binary/dev_lcd_s1d13506.o

4. modify your skyeye.conf like:
....
lcd: type=s1d13506


BTW, I'd clean-up the lcd device framework,
maybe you should update your source of SkyEye from SVN.

I don't know how to do that. :)
