gw: fix synthesis
...
Still unclear what exactly this fixes, I think mostly bugs in
migen/LiteX. Not sure if it's synthesizing the memory elements for the
sampler modules either.

Just need to hook this into the FIFO I made before, and write all the
peak detection, triggering, and trigger enable logic, + hook everything
into a single wishbone address space.

gateware: move back to LiteX

Had too many issues with integrating LiteEth. I put my FW into a LiteX
SoC and it worked, so I migrated back. With the knowledge I gained doing
Amaranth I could fix the issues I had adding a wishbone slave device
pretty easily.

gateware: fix dumb mistakes
...
Bus widths should now all be correct. (addresses and sizes in amaranth
take into account the granularity selection, so granularity acts like
two extra bits on the bus address line)
Also don't ignore a warning about undriven resets. Turns out that can
gate *everything* off in your design.
