The DIU_DIV register is 8 bit not 5 bit. This prevented large DIV values
so it was not possible to set a slow pixel clock and thus prevented
display on small screens.

Add cfb console support to FSL 8610 DIU driver.
Inspect board version from PIXIS to obtain correct pixel format.
Use #define CONFIG_VIDEO in config file to enable fb console.
To switch monitor, set monitor variable to
0 - DVI, 1 - Single link LVDS, 2 - Double link LVDS
followed by "diufb init".
Preserve logo bitmap at the top of the fb console.

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.
