Bring in device tree files for ls1021a from linux V3.19. In order to use it in u-boot, make some changes: 1. remove 'gic' node and interrupt related properties in every node. 2. remove 'clockgen' node and clock related properties in every node. 3. change address-cells and size-cells of root node and 'soc' node from 2 to 1. 4. Add quadspi node.
