boards/sipeed-longan-nano: improve ADC config

Browse Source 
The ADC configuration was too complex. It was hard to follow when certain ADC lines are available. Furthermore, the order of ADC lines did depend on the use of other peripherals. Now, either the TFT display is not connected and all ADC lines are available or the TFT display is connected and the second SPI device is used so that only the first 4 ADC lines are available.
