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.
