armv8: fsl-layerscape: Add support of QorIQ LS1012A SoC

The QorIQ LS1012A processor, optimized for battery-backed or
USB-powered, integrates a single ARM Cortex-A53 core with a hardware
packet forwarding engine and high-speed interfaces to deliver
line-rate networking performance.

This patch add support of LS1012A SoC along with
 - Update platform & DDR clock read logic as per SVR
 - Define MMDC controller register set.
 - Update LUT base address for PCIe
 - Avoid L3 platform cache compilation
 - Update USB address, errata
 - SerDes table
 - Added CSU IDs for SDHC2, SAI-1 to SAI-4
