- fix a copy-paste error (`TIMER_FREQ_UART_TEST` was used in the SPI test, but that should be `TIMER_FREQ_SPI_TEST`) - use 400 kHz as slow SPI frequency, as faster STM32 MCUs just cannot divide the APB clock down to 100 kHz - when detailed output is enabled, print the SPI clock in addition to the SPI mode to ease figuring out what went wrong - only have one `FAILURE` message for a too fast byte transfer per check, rather than per transmitted byte, to reduce the noise - work around a bug of `periph_timer` on STM32 by reducing the clock speed of the timer for the SPI test
