Fabio Estevam 2740e5de4f video: ipu_disp: Fix clock polarity logic 
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.
