armv8: lx2160a: Add LX2160A SoC Support

LX2160A Soc is based on Layerscape Chassis Generation 3.2
architecture with features:
 16 ARM v8 Cortex-A72 cores in 8 cluster, CCN508, SEC,
 2 64-bit DDR4 memory controller, RGMII, 8 I2C controllers,
 3 serdes modules, USB 3.0, SATA, 4 PL011 SBSA UARTs,
 4 TZASC instances, etc.

SoC personalites:
LX2120A is SoC with Twelve 64-bit ARM v8 Cortex-A72 CPUs
LX2080A is SoC with Eight 64-bit ARM v8 Cortex-A72 CPUs
