arm: ls102xa: Add Freescale LS102xA SoC support

The QorIQ LS1 family is built on Layerscape architecture,
the industry's first software-aware, core-agnostic networking
architecture to offer unprecedented efficiency and scale.

Freescale LS102xA is a set of SoCs combines two ARM
Cortex-A7 cores that have been optimized for high
reliability and pack the highest level of integration
available for sub-3 W embedded communications processors
with Layerscape architecture and with a comprehensive
enablement model focused on ease of programmability.
