Sylvain Munaut 641ac1e3ef gateware: Switch to using Vex CPU
It's a good ~ 3.5x faster than the PicoRV32 (in number of cycles),
which allows to shutdown the system clock more and reduce power
a bit as well.

Sylvain Munaut 119bc9fa1f gateware: Switch to using the _3 variant of system manager
This alone seems to reduce by ~30% the power usage of the SoC
(when USB is off).
