Introduce basic support for the Freescale P1022DS reference board, based on the
Freescale BSP for this board.

Details: No DIU video or SSI audio support, no MMC/SD card support, 36-bit and
SWIOTLB support enabled, 36-bit DTS only, and CONFIG_NO_HZ disabled because it
causes performance problems on this kernel.

what kind of performance problems?

See my post on linuxppc-dev about CONFIG_NO_HZ.

these queue-group nodes, fsl,{r,t}x-* properties...

I just copied this tree from the BSP.  I have no idea what they should ok 
like.  Can you be more specific?

and the above two properties aren't supported by their respective
drivers, nor are they listed in the dts bindings documentation.

Then please tell me what these nodes should look like.
