From: Geert Uytterhoeven <geert+renesas@glider.be> Add device nodes for the L2 caches, and link the CPU nodes to them. The L2 cache for the Cortex-A15 CPU cores is 2 MiB large (organized as 128 KiB x 16 ways). The L2 cache for the Cortex-A7 CPU cores is 512 KiB large (organized as 64 KiB x 8 ways).
