Currently the HDMI splash screen image quality on mx6solo does not show a
very stable image.
By comparing the IPU driver from U-boot with the one from FSL 4.1.0 BSP,
we can see that there is an inverted logic for setting the DI_GEN_POL_CLK bit.
>From FSL BSP [1] we have:
if (!sig.clk_pol)
di_gen |= DI_GEN_POLARITY_DISP_CLK;
Applying the same logic into U-boot fixes the HDMI image stability.

to use this driver also on am335x based boards, the following
changes are made:
- struct lcd_ctrl_config lcd_cfg is now configurable
through board code
- controller base is configurable through define
DA8XX_LCD_CNTL_BASE. To be compatible with older
da8xx based boards: If this define is missing, the
DAVINCI_LCD_CNTL_BASE is used
- Determine LCD IP Version, and make the driver

May be, the file smdk5250.c can be removed in near future

NOTE:
Please note that all additions corresponding to FDT need to be added into the
