Convert the bindings of the Freescale Pixel Pipeline to YAML.

The conversion drops the previously listed compatibles for several SoCs.
It is unclear, if the PXP on these SoCs is compatible to any of the PXPs
on the existing SoCs and would allow to reuse the already defined
compatibles. The missing compatibles should be brought back when the
support for the PXP on these SoCs is added.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

I am surprised that these warnings didn't show up when I ran 'make
dtbs_check'. I will check if there is something wrong with my setup.

This is an error in the schema. I dropped the fsl,imx6sll-pxp and
fsl,imx6sx-pxp compatibles, because I thought that they aren't used.

I will send a v2 to fix the schema.

Can you make the number of items conditional on the compatible string ?

I think this could be simplified to

  clock-names:
    const: axi

Up to you.

-Freescale Pixel Pipeline
-========================

-The Pixel Pipeline (PXP) is a memory-to-memory graphics processing engine

-Required properties:

-- clock-names: should be "axi"
-- clocks: the PXP AXI clock
