if_atsam: Recover from receive freezes
...
Under unknown conditions the receive path ended up in a frozen state.
In this state, the DMA and driver descriptor head were equal and all
receive descriptors had the used bit set. So, the DMA was unable to
store received frames. However, the receive daemon was never woken up
to refill the receive buffers. It seems that the RXUBR interrupt can be
used to recover from this state.

Do not use the interface mutex in the receive loop. Avoid multiple
reads of DMA descriptor words. Use a compile-time constant for the
receive DMA descriptor count to simplify calculations.
