powerpc/mpc85xx:Make L2 cache type independent of CHASSIS2
CHASSIS2 architecture never defines type of L2 cache present in SoC. it is dependent upon the core present in the SoC. for example, - e6500 core has L2 cluster (Kibo) - e5500 core has Backside L2 Cache Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com>
