cxgb4: Replaced the backdoor mechanism to access the HW memory with PCIe Window method
Rip out a bunch of redundant PCI-E Memory Window Read/Write routines, collapse the more general purpose routines into a single routine thereby eliminating the need for a large stack frame (and extra data copying) in the outer routine, change everything to use the improved routine t4_memory_rw.
