The newly added runtime PM support for the cadence spi driver
causes harmless warnings when PM is disabled:
drivers/spi/spi-cadence.c:681:12: warning: 'cnds_runtime_suspend' defined but
not used
drivers/spi/spi-cadence.c:652:12: warning: 'cnds_runtime_resume' defined but
not used
This adds __maybe_unused annotations to the respective functions
to shut up the warnings, while leaving the code in place for
compile testing and avoiding ugly #ifdefs.
