spi: fsl_qspi: Ensure width is respected in spi-mem operations

Browse Source 
Adapted from kernel commit b0177aca7aea
From: Michael Walle <michael@walle.cc>

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.

Fixes: 91afd36f38 ("spi: Add a driver for the Freescale/NXP QuadSPI controller")
