Subject: [PATCH v5 2/9] arm64: dts: Reflect change of FSL QSPI driver and
 remove unused properties

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 'num-cs' and 'bus-num' were never read by the
driver and can be removed.

The property 'fsl,qspi-has-second-chip' is not needed anymore
and will be removed after the old driver was disabled to avoid
breaking fsl-ls1046a-rdb.dts.
