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.
