armv8: ls1012a: Add support of ls1012ardb board

QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance
development platform, with a complete debugging environment.
The LS1012ARDB board supports the QorIQ LS1012A processor and is
optimized to support the high-bandwidth DDR3L memory and
a full complement of high-speed SerDes ports.

+
+LS1012A SoC Overview
+--------------------
+Please refer arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc for LS2080A
+SoC overview.
+
+LS1012ARDB board Overview
+-----------------------
+ - SERDES Connections, 4 lanes supporting:
+      - PCI Express - 3.0
+      - SGMII, SGMII 2.5
+      - SATA 3.0
+ - DDR Controller
+     - 16-bit, 1 GB DDR3L SDRAM memory, running at data rates up to 1 GT/s
+ -QSPI: A dual 1:3 switch, NX3L4357GM,115 (U35) drives the QSPI chip-select
+ signals to
+    - QSPI NOR flash memory (2 virtual banks)
+    - the QSPI emulator.s
+ - USB 3.0
+    - one high-speed USB 2.0/3.0 port.
+ - Two enhanced secure digital host controllers:
+    - SDHC1 controller can be connected to onboard SDHC connector
+    - SDHC2 controller: Three dual 1:4 mux/demux devices,
+    74CBTLV3253DS (U30, U31, U33) drive the SDHC2 signals to eMMC,
+    SDIO WiFi, SPI, and Ardiuno shield
+ - 2 I2C controllers
+ - One SATA onboard connectors
+ - UART
+   - The LS1012A processor consists of two UART controllers,
+   out of which only UART1 is used on RDB.
+ - ARM JTAG support
+
+Booting Options
+---------------
+a) QSPI Flash Emu Boot
+b) QSPI Flash 1
+c) QSPI Flash 2
+
