[POWERPC] Make it blatantly clear; mpc5200 device tree is not yet stable

From: Grant Likely <redacted>

Documentation-only change.  The 5200 device tree layout has not yet
stablized, so nobody should depend on the layout of the tree.

Paul,

(minor rework from comments received)

I know it's *very* late in the .20 release cycle, but I don't want to
allow false assumptions about the stability of the 5200 device tree
bindings.

Please apply for 2.6.20 If you think it is appropriate.

Thanks,
g.
