spi: spi-fsl-dspi: Enable support for S32G platforms

Add compatible for S32G platforms, allowing DSPI to be used.

Add a depends for ARCH_NXP which can replace LAYERSCAPE and also
includes the new ARCH_S32 for S32G. Similarly, ARCH_MXC can replace
SOC_VF610 || SOC_LS1021A which should avoid updating this for every new
sub-platform in the future.
