Due to limited value of clock divider, fast SPI instance can work only at higher bitrates. Add check for error message when fast instance is configured to work at low/unsupported bitrate. Signed-off-by: Sebastian Głąb <[email protected]>

Driver was silently failing when unsupported (too low) bitrate was selected on fast SPI instance. On nrf54H20dk, lowest supported bitrate for SPI120/SPI121 is: On nrf54l15dk, lowest supported bitrate for SPI00 is: |
