After cleaning up the default config of SPI, this commit cleans up the configuration for `sipeed-longan-nano` a bit: - PA4 is no longer used as default CS for `SPI_DEV(1)` - At least one DAC channel PA4 is always available if DAC is used. - PA4 is always available as ADC channel if DAC is not used. - The order of ADC and DAC channels has been changed accordingly.
