512ed2b3d6 Preliminary AXI4Lite CSR bridge support 
This change introduces an AXI4Lite to CSR bridge. Hopefully it will
become extended in the future with full AXI support and more structures
(Wishbone bridge, interconnect, ...). For now this will do.

The bridge has been simulated (and includes an FHDL testbench) and
tested in hardware (on a Zynq 7020).
