[RFC][PATCH 09/30] powerpc/85xx: Rework P1020RDB device tree

[Kumar Gala <galak@kernel.crashing.org>]

We split out the common bits of the P1020RDB device tree such that we
can reuse those bits between a 32-bit or 36-bit address map device tree.

We also update the P1020RDB device tree to utilize the new p1020 SoC dts
includes (fsl/p1020si-pre.dtsi & fsl/p1020si-post.dtsi).
