They were getting this implicitly by an include of module.h
from device.h -- but we are going to clean that up and break
that include chain, so include module.h explicitly now.

Since commit a19a6ee "backlight: Allow properties to be passed at
registration" and commit bb7ca74 "backlight: add backlight type", we can
set backlight type and max_brightness before backlights are registered.
Some newly added drivers did not set it properly, let's fix it.

Add the ams369fg06 amoled panel driver. The ams369fg06 amoled panel (480
x 800) driver uses 3-wired SPI inteface. The brightness can be controlled
by gamma setting of amoled panel.

There may be multiple ways of controlling the backlight on a given
machine. Allow drivers to expose the type of interface they are
providing, making it possible for userspace to make appropriate policy
decisions.

sysfs attribute file in s6e63m0_remove
s6e63m0_probe() registered backlight device and create sysfs attribute
files, thus s6e63m0_remove() should unregister backlight device and remove
sysfs attribute files.

This is S6E63M0 AMOLED LCD Panel(480x800) driver using 3-wired SPI
interface also almost features for lcd panel driver has been implemented
in here. and I added new structure common for all the lcd panel drivers
to include/linux/lcd.h file.
LCD Panel driver needs interfaces for controlling device power such as
power on/off and reset. these interfaces are device specific so it should
be implemented to machine code at this time, we should create new
structure for registering these functions as callbacks and also a header
file for that structure and finally registered callback functions would be
called by lcd panel driver. such header file(including new structure for
lcd panel) would be added for all the lcd panel drivers.
If anyone provides common structure for registering such callback
functions then we could reduce unnecessary header files for lcd panel. I
thought that suitable anyone could be include/linux/lcd.h so a new
lcd_platform_data structure was added there.
