Add nodes and properties for QSPI controller. Add support for spansion flash, s25fs512s, as slave device for QSPI controller. Added entry of "fsl,ls1088a-qspi" in fsl-quadspi.txt binding file.

Send me dts patch only after driver and bindings doc get merged.
Changes for v2: - Move property spi-rx-bus-width and spi-tx-bus-width from controller to connected slave device node. .../devicetree/bindings/mtd/fsl-quadspi.txt | 1 +
The bindings doc shouldn't be part of dts patch. Shawn
