GRSPW: New packet based driver for SPW/SPW2/SPW2_DMA
This patch adds a new driver for the GRSPW SpaceWire AMBA
interface family. The new driver does not implement a standard
RTEMS driver, instead it provides only a library interface to
the GRSPW devices. This driver can be used to implement a
RTEMS I/O driver or used directly.
New features compared with old GRSPW driver:
* zero-copy packet interface
* possibility to send/receive mulitple packets per call
* optional interrupt awaken work-task to process TX/RX queues
* DMA channels support. Before only first DMA channel supported
* Separate DMA and link control
* Packet based error flags
