DT and driver changes for DSPI on S32G platforms. First 4 commits add
new S32G registers and device settings along with restricting userspace
register access properly for all devices. Then some DMA mode fixes along
with adding support for target mode, which uses DMA. Followed by some
other minor bug fixes and then finally add the DT compatibles and
binding docs.
