B4860 has 1 PPC core cluster and 3 DSP core clusters.
Similarly B4420 has 1 PPC core cluster and 1 DSP core cluster.

Each DSP core cluster consists of 2 SC3900 cores and a shared L2 cache.

1. Add DSP clusters for B4420
2. Reorganized the L2 cache nodes such that they now appear in only the
soc specific dtsi files(b4860si-post.dtsi and b4420si-post.dtsi).
Earlier they were shown partly in common b4si-post.dtsi and si specific
b4860si-post.dtsi files .
