"fsl,P2020RDB-PC" compatible string was present in Turris 1.x DTS file just
because Linux kernel required it for proper detection of P2020 processor
during boot.

This was quite a hack as CZ,NIC Turris 1.x is not compatible with
Freescale P2020-RDB-PC board.

Now when kernel has generic unified support for boards with P2020
processors, there is no need to have this "hack" in turris1x.dts file.

So remove incorrect "fsl,P2020RDB-PC" compatible string from turris1x.dts.
Oh, I thought it was not possible to modify DTSes.

If it is, can you have a common compatible to all p2020, for instance 
"fsl,p2020', so that you can use it in patch 5 instead of 
of_find_node_by_path("/cpus/PowerPC,P2020@0") ?
