c7fc57213c Avoid releasing trap signal too early 
The trap signal is used my the mux in serv_rf_if to decide which
registers to write to. If the trap signal is dropped too early,
the destination address changes while the register is still being
written to.

c6e5053c78 Clean up RISCOF support structure 
The RISCOF regression test suite can now be run from a workspace instead
of having to be run from inside the repo. Also removes the need for a
submodule.

8edd456b5d Rewrite serv_rf_ram_if 
This adds some optimizations to serv_rf_ram_if. It also adds a read enable
signal and delays writes one cycle which has the added bonus that no reads
or writes happen in the same cycle for RF_WIDTH > 2. This allows SERV to be
used with single-port RAMs in most cases.
