From: Frieder Schrempf <redacted> The FSL QSPI driver will be moved to the SPI framework and it then acts as a SPI controller. Therefore the subnodes need to set spi-[rx/tx]-bus-width = <4>, so quad mode is used just as before. Also the properties 'bus-num', 'fsl,spi-num-chipselects' and 'fsl,spi-flash-chipselects' were never read by the driver and can be removed. The 'reg' properties are adjusted to reflect what bus and chipselect the flash is connected to, as the new driver needs this information. The property 'fsl,qspi-has-second-chip' is not needed anymore and will be removed after the old driver was disabled to avoid breaking ls1021a-moxa-uc-8410a.dts.
