This LCD driver is for the LCD controller in the S3C2410/S3C2440 CPUs only.
Change its name to reflect its usage and free the way to add LCD controller
drivers for more recent Samsung CPUs.

Add all available video modes to the framebuffer. devinfo fb0
shows the available modes. We can select a mode now.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.

Video controller of STM allow to control the reset bit of an external
LCD controller. When reset_lcd is set, CTRL1_RESET bit is used to
enable and disable LCD.
Handle USE_LCD_RESET as a flag in imx_fb_platformdata.

When describing an new video interface, it is now possible to select
the bit per pixel. If nothing is chosen 16bpp is selected by default.

We never supported the sigmatel stm chips and probably
never will. So do the first step and rename the architecture
to mxs just like in the kernel.

Also, set size to 0 when setting up the framebuffer failed so that
the user cannot write to uninitialized framebuffer memory.

Calling fb_activate_var potentially changes the framebuffer address,
so we have to update the fb0 cdev afterwards.

This patch add the possibility to change the video mode at barebox's runtime
if the graphics driver in use supports it.

To setup the default 'enable' setting the "dev_set_param(dev, "enable", "0");"
does not work as expected. After the call the parameter is still "<NULL>".
This is due to any change of the setting is rejected, if the same setting
is already active.
This patch also let the default setting be successfull, but only calls the
graphics backend if a change happens.

The bitfield information was only added to fb_info when the
framebuffer actually was enabled. That made it impossible to
call 'bmp' before enabling the display.
So, move all fb_info init to a single place and make it a function
to better allow for multiple displays later.

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.
