QuadSPI controller supports Single, dual, quad modes of operation.
Mode is controlled via either RCW or the on-board connection to flash.

spi-tx-bus-width, spi-rx-bus-width binding added to define mode
of operation. Definition of these binding are standard as defined
in Documentation/devicetree/bindings/spi/spi-bus.txt.
