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.

After switching to the new FSL QSPI driver the property
'fsl,qspi-has-second-chip' is not needed anymore.
The driver now uses the 'reg' property to determine the bus and
the chipselect.
