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.
