spi: nxp_fspi: Ensure width is respected in spi-mem operations
Import linux commit 007773e16a6f ("spi: nxp-fspi: Ensure width is
respected in spi-mem operations") to fix SPI access on boards which
don't have all SPI I/O lines connected to the flash.
Since commit 71025f013ccb ("mtd: spi-nor-core: Rework hwcaps selection")
u-boot figures out the capabilities by looking at spi_mem_supports_op().
The FlexSPI driver doesn't take the board layout into account. Fix that.
Fixes: 383fded70c4f ("spi: nxp_fspi: new driver for the FlexSPI controller")
