While chasing in_interrupt() (ab)use in drivers it turned out that the caif_spi driver has never been in use since the driver was merged 10 years ago. There never was any matching code which provides a platform device. The driver has not seen any update (asided of treewide changes and cleanups) since 8 years and the maintainers vanished from the planet. So analysing the potential contexts and the (in)correctness of in_interrupt() usage is just a pointless exercise. Remove the cruft.
