Michal Lenc ce53ea5da6 arch/arm/src/samv7: add DMA and TC trigger support to AFEC driver
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.
