spi: spi-fsl-dspi: Revert unintended dependency change in config SPI_FSL_DSPI

Commit 9a30e33 ("spi: spi-fsl-dspi: Enable support for S32G
platforms") reworks the dependencies of config SPI_FSL_DSPI, but introduces
a typo changing the dependency to M5441x to a dependency on a non-existing
config M54541x.

Revert the unintended change to depend on the config M5441x.
