Merge branch 'peter_clbv2_ref_design' of ohwr.org:hdl-core-lib/wr-cores into peter_clbv2_ref_design
clk_20m_vcxo_i free running clock for reset gen. (thus no need for separate 125 MHz fpga input; remove clk_125m_pllref_p/n_i)

Fixed by adding missing "else statement" in CRC_WORD state. In this
statement the dvalid is set LOW and no ('X') data is set. Without
this, the input data remainded 0xCAFE and the input dvalid remainded
HIGH, thus the escape_inserter was forcing dreq=LOW in order to
stop the input data for one cycle and insert special character.

c0e116b: simpler sdbfs creation by using parameters provided by Syscon HDL module

The streamer has a new start-up delay counter. this delay needs to be
shorter for simulation. the fact that we are running simulation was not
passed to the Tx streamer, now it is passed.

by default, the bram content for synthesis is specified. it is only
overriden by simulation. In this way, if the top can be both, simulated
and synthesized.

The binary did not work. I do not know why. I just recompiled wrpc-sw
with wrpc_sim_defconfig configuration and it works.
