atlys: add 2-clock synchronizer chain for ddr2_calib_done
The signal ddr2_calib_done signal comes from the ddr2 clock domain,
while wb_req is treating it as if it came from wb_clk domain. As a
result the timing analysis tool assumed a worst case scenario of 5ns
between the two domains and the results were miserable.
While we can argue that this is a multi-cycle path, the fact is that
ddr2_calib_done feeds into multiple logic sinks and can potentially
cause meta-stability issue in the design. The solution is to add a
2-clock meta-stability filter to address both the timing problems and
the meta-stability concern.

ORPSoC: The ability to use a free/gimped version of Modelsim was restricted to
the reference build's scripts. This patch adds support for it to the
scripts for the board builds as well.
