powerpc/b4860: Renamed the L2 caches

To make provision for more than one L2 caches in the system, change the
name from L2 to L2_1; same as in T4 platforms.
* Also remove the L2 entry from common file
"arch/powerpc/boot/dts/fsl/b4si-post.dtsi"
Keep them only in separate files for b4860 and b4420.

powerpc/fsl-booke: Add initial silicon device tree files for B4860 and B4420

B4860 and B4420 are similar that share some commonalities

* common features have been added in b4si-pre.dtsi and b4si-post.dtsi
* differences are added in respective silicon files of B4860 and B4420

There are several things missing from the device trees of B4860 and B4420:

* DPAA related nodes (Qman, Bman, Fman, Rman)
* DSP related nodes/information
* serdes, sfp(security fuse processor), thermal,
gpio, maple, cpri, quad timers nodes
