Still more when imx51 support is added which has two different spi interfaces which would introduce additional checks on the device id. With this setup it's not possible for the compiler anymore to detect the unused functions, so four additional kconfig symbols are introduced to ifdef out the unneeded functions in the callback array and all these functions are marked with __maybe_unused to suppress the corresponding gcc warnings.
