[POWERPC] mpc5200: normalize compatible property bindings
Update MPC5200 drivers to also look for compatible properties in the form "fsl,mpc5200-*" to better conform to open firmware generic names recommended practice as published here: http://www.openfirmware.org/1275/practice/gnames/gnamv14a.html This patch should *not* break compatibility with older device trees which do not use the 'fsl,' prefix. The drivers will still bind against the older names also. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
