commit dd1053a93fdc11d4 ("spi/drivers: Enable build of drivers with
COMPILE_TEST") allows compile-testing drivers on platforms they're not
meant for.

However, adding "|| COMPILE_TEST" bypasses all other implicit dependencies
assumed by the platform dependencies before, like HAS_DMA.

If NO_DMA=y:

Add dependencies on HAS_DMA to fix this.
