74f89faa9d Move 8610 DIU interface structure definitions to header file.
These two structures are still needed during the
initialization and setup of the DIU hardware.
So move them to the fsl_diu_fb.h file for now.
Official "blah".

a877880c69 8610: Add 8610 DIU display driver
1280x1024 and 1024x768 @ 32 bpp are supported now.
DVI, Single-link LVDS, Double-link LVDS are all supported.

Environmental variable "monitor" is used to specify monitor port.

A new command "diufb" is introduced to reinitialize monitor
and display a BMP file in the memory. So far, 1-bit, 4-bit,
8-bit and 24-bit BMP formats are supported.

    diufb init
        - initialize the diu driver
    Enable the port specified in the environmental variable "monitor"

    diufb addr
        - display bmp file in memory.
    The bmp image should be no bigger than the resolution, 1280x1024
    for DVI and double-link LVDS, 1024x768 for single-link LVDS.

Note, this driver allocate memory but doesn't free it after use
It is written on purpose -- to avoid a failure of reallocation
due to memory fragement.

ECC of DDR is disabled for DIU performance. L2 data cache is also disabled.
