netxen: implement generic pcie semaphore functions
Implement common function for locking/unlocking 8 hardware semaphores used for serializing access to shared resouces on a NIC board by different PCI functions. As by definition, callers of these semaphore API can be put to sleep till the semaphore is locked. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
