armv8: ls1012a: Add support of ls1012aqds board

QorIQ LS1012A Development System (LS1012AQDS) is a high-performance
development platform, with a complete debugging environment.
The LS1012AQDS 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.

+    - SDHC1 controller can be connected to onboard SDHC connector
+    - SDHC2 controller: 1-/4-bit SD/MMC card supporting 1.8 V devices
+ - 2 I2C controllers
+ - One SATA onboard connectors
+ - UART
+ - 5 SAI
+    - One SAI port with audio codec SGTL5000:
+	• Provides MIC bias
+	• Provides headphone and line output
+    - One SAI port terminated at 2x6 header
+    - Three SAI Tx/Rx ports terminated at 2x3 headers
