spi: spi-fsl-lpspi: Generic fixes and support for

Merge series from James Clark <james.clark@linaro.org>:

Various fixes for LPSI along with some refactorings. None of the fixes
are strictly related to S32G, however these changes all originate from
the work to support S32G devices. The only commits that are strictly
related are for the new s32g2 and s32g3 compatible strings.
