ARM: dts: r8a73a4: Add L2 cache-controller nodes
Add device nodes for the L2 caches, and link the CPU node to its L2 cache node. The L2 cache for the Cortex-A15 CPU cores is 1 MiB large (organized as 64 KiB x 16 ways), and located in PM domain A3SM. The L2 cache for the Cortex-A7 CPU cores is 512 KiB large (organized as 64 KiB x 8 ways), and located in PM domain A3KM.
