Anton Blanchard aa1d2b16d7 litedram: Regenerate
Regenerate from upstream litex. Something in the update has improved
memory read and write performance quite a lot on my Nexys Video:

Before:

  Write speed: 83.2MiB/s
   Read speed: 140.4MiB/s

After:

  Write speed: 352.1MiB/s
   Read speed: 218.5MiB/s

Note: There are a few patches to upstream to fix an upstream breakage
of litedram standalone generator, and fix some issues with liteeth
in the way it's used on Wukong. All these have pending pull requests.
