When compile-testing the pwm driver without also enabling the stm32_timers MFD, we run into a link error:
drivers/pwm/pwm-stm32.o: In function `stm32_pwm_raw_capture.isra.6': pwm-stm32.c:(.text+0xcb0): undefined reference to `stm32_timers_dma_burst_read' We don't need the '|| COMPILE_TEST' here, since stm32_timers itself can be built with CONFIG_COMPILE_TEST on all architectures, so we do get the coverage through allmodconfig and randconfig builds even when we make it a hard dependency.
