powerpc/85xx: Simplify P1020RDB CAMP dts using includes
If we include the p1020rdb.dts instead of p1020si.dts we greatly reduce duplication and maintenance. We can just list which devices are disabled for the given core and mpic protected sources. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
