e64417cfb1 litex: litex_boards: sync with master to fix import issue 
The previous version of `litex_boards` was unable to import certain
packages without setuptools, due to unrelated imports being included.

This latest version fixes that issue, and allows for the fomu-toolchain
to work with the `litex_boards` repo.

3a96d67339 litex: enable git updating for workshop and workshop_rgb

Internet access.  However, it's better to keep it enabled for general
use.
