This commit adds DMA and TC support to SAMV7 AFEC driver. The AFEC (ADC) can now be triggered by Timer/counter at chosen frewuency and samples can be transfered via DMA with configurable number of samples. Timer/counter trigger is now set as a default option with the possibility to change it to software generated trigger. DMA is inspired by SAMA5 driver and also uses ping pong buffers.
