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).

Specify top-level module in Lattice Diemond build script.
...
When building multi-source files the toolchain gets confused as to which
module is top-level. This ensures that the build_name of the design is
selected.

Build top module as 'dut' in Verilator and set it as top-level.
...
When building a design with PicoRV32 we end up with multiple top-level
modules and Verilator becomes confused as to which is the right one.
This change ensures the dut.v generated by the sim build process has
it's top-level name set to 'dut' and that verilator is invoked with this
name.

Allow for multiple synthesis directives in specials.
...
This is needed to specify timing constraints on some Lattice Diamond
library specials, like the EHXPLLL.
To keep backwards compatibility we allow the directive to still be a
single string. If it's not, we assume it's an iterable.
