armv8: ls1046afrwy: Add support for LS1046AFRWY platform

LS1046AFRWY board supports LS1046A family SoCs. This patch
add base support for this board.
Board support's 4GB ddr memory, i2c, micro-click module,microSD card,
serial console,qspi nor flash,ifc nand flash,qsgmii network interface,
usb 3.0 and serdes interface to support two x1gen3 pcie interface.

+Overview
+--------
+The LS1046A Freeway Board (iFRWY) is a high-performance computing,
+evaluation, and development platform that supports the QorIQ LS1046A
+LayerScape Architecture processor. The FRWY-LS1046A provides SW development
+platform for the Freescale LS1046A processor series, with a complete
+debugging environment. The FRWY-LS1046A  is lead-free and RoHS-compliant.
