Instead of hard-coding data and address width to 32, assert that
the AXI and Wishbone interfaces have *matching* address and data
widths.

build/lattice/trellis: also generate bitstream in svf format
...
Before being able to program the board (e.g., with openocd), one
would have to convert the bitstream file to .svf using a python
script included with the source trellis distribution. However,the
trellis 'ecppack' utility can also generate .svf bitstream files
directly.

versa_ecp5: Remove negative diff IO pins
...
In Lattice FPGAs only the positive side of differential pairs should
be specified (unlike Xilinx)
These are a warning on Diamond (which trims unused IO) and an error
with Yosys/nextpnr (which doesn't so they conflict when the positive
pin is 'expanded').
Already this is the case for the clock input, this commit performs
the same change for the DDR3 pins.
