Subject: [PATCH] spi: spi-fsl-qspi: Ensure width is respected in spi-mem
operations
commit b0177aca7aea7e8917d4e463334b51facb293d02 upstream.
Make use of a core helper to ensure the desired width is respected
when calling spi-mem operators.
Otherwise only the SPI controller will be matched with the flash chip,
which might lead to wrong widths. Also consider the width specified by
the user in the device tree.
