leon, grspw_router: Changed driver C API

SMP safe by spin-lock protection and semaphore. On spin-lock per SpW/AMBA
port to allow multiple parallel register operations per port. A common
semaphore for general SpW router configuration such as routing table.

Move to a C API instead of using the I/O Manager. The SpW router driver
does not perform any I/O only management of the router.

Update #2355.
