Currently the scripts use 'analog.com' as the vendor property for IP cores,
but 'ADI' for interfaces.
Make things consistent by using 'analog.com' for both interfaces as well
as IP cores.

Currently the clock monitor features a hold register in the monitored clock
domain. This old register is used to store a instantaneous copy of the
counter register. The value in the old register is then transferred to the
monitoring domain. Since the counter is continuously counting it is not
possible to directly transfer it since that might result in inconsistent
data.
Instead stop the counter and hold the registers stable for a duration that
is long enough for the monitoring domain to correctly capture the value.
Once the value has been transferred the counter is reset and restarted for
the next iteration.
This allows to eliminate the hold register, which slightly reduces
utilization.
The externally visible behaviour is identical before and after the patch.

All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.
New license looks as follows:

Can not be multiple 'if' statements inside a generate block. If there are
multiple cases use if/esle statement, but always should be one single
if/else inside a generate.
Currently the IDDRs are configured in SAME_EDGE_PIPELINED mode, but then
the negative data is delayed by an additional clock cycle. This is the same
behaviour as using the IDDR in SAME_EDGE mode.
Switching to SAME_EDGE mode removes extra pipelining registers while
maintaining the same behaviour.

Xilinx recommends that all synchronizer flip-flops have
their ASYNC_REG property set to true in order to preserve the
synchronizer cells through any logic optimization during synthesis
and implementation.
- Change the clock and reset port name of the AXI slave interface
to s_axi_aclk and s_axi_aresetn. This way we can use the adi_ip_properties
process to infer the interface.
- Define an address space reference to the m_axi interface.
In modules ad_serdes_in/ad_serdes_out the handover of the parameter
SERDES_FACTOR did not exist, causing unwanted behavioral in case of
factors less than 8.
SERDES_FACTOR must be hand over to DATA_WIDTH parameter of the SERDES
primitive.
