Subject: [PATCH 4/5] arm64: dts: Add spi-[tx/rx]-bus-width for the FSL QSPI
controller
From: Frieder Schrempf <frieder.schrempf@...tron.de>
We will move the FSL QSPI driver to the SPI framework soon. To
prepare and to make sure the full buswidth is used (as it is with
the current driver), let's add the right properties.
