target-arm: cpu64: Add support for Cortex-A53
Add the ARM Cortex-A53 processor definition. Similar to A57, but with different L1 I cache policy, phys addr size and different cache geometries. The cache sizes is implementation configurable, but use these values (from Xilinx Zynq MPSoC) as a default until cache size configurability is added. Acked-by: Edgar E.
