cxgb4: Common platform specific changes for DB Drop Recovery
Add platform-specific callback functions for interrupts. This is needed to do a single read-clear of the CAUSE register and then call out to platform specific functions for DB threshold interrupts and DB drop interrupts. Add t4_mem_win_read_len() - mem-window reads for arbitrary lengths. This is used to read the CIDX/PIDX values from EC contexts during DB drop recovery. Add t4_fwaddrspace_write() - sends addrspace write cmds to the fw. Needed to flush the sge eq context cache.
