arm: ls102xa: Add basic support for LS1021AQDS board
LS102xA is an ARMv7 implementation. This patch is to add
basic support for LS1021AQDS board.
One DDR controller
DUART1 is used as the console
For the detail board information, please refer to README.

+ * This file handles the board muxing between the RGMII/SGMII PHYs on
+ * Freescale LS1021AQDS board. The RGMII PHYs are the three on-board 1Gb
+ * ports. The SGMII PHYs are provided by the standard Freescale four-port
+ * SGMII riser card.
+ *
+ * Muxing is handled via the PIXIS BRDCFG4 register. The EMI1 bits control
+ * muxing among the RGMII PHYs and the SGMII PHYs. The value for RGMII depends
+ * on which port is used. The value for SGMII depends on which slot the riser
+ * is inserted in.
