leon, grspw_pkt: support for reading tx/rx DMA queue
* Add support for reading the GRSPW TX/RX descriptor counters
directly.
* Add semaphore lock to counters to avoid couters being out
of sync
* This makes it possible for the user in polling mode to check
the amount of work before entering RX/TX descriptor table
processing.
