   ## Summary
   stm32,stm32f7: add support for BEMF sensing
   
   Relate issue: https://github.com/apache/nuttx/issues/8098
   
   ## Testing
   b-g431b-esc1
   Below example of BEMF reconstructed for a random drone motor rotated by hand. Samples are just int16_t values without any further conversion.
   
   The pink line shows virtual ground calculated from equation `Vzero = (Va + Vb + Vc)/3`, the others are `V1 = Va - Vzero`, `V2 = Vb  - Vzero` and `V3 = Vc - Vzero`
