Improved Back-End write-channel for both Native and AXI (reduces consecutive writes by 1 clock-cycle
Added define CTRL_IO that allows the implementation of a i/o forced invalidate signal (allowing a L1 to invalidate the L2), and a i/o for the write-buffer empty status (allowing for the L1 also return the fact the L2 is also empty). Mono-cache systems can disable this define in hardware/include/iob_cache.vh.
