Add a parameter to the ad_xcvrcon function that allows to provide a mapping
between logical and physical lanes. By default if no lane map is provided
the logial and physical lanes are mapped 1-to-1. If a lane map is provided
logical lane $n is mapped onto physical lane $lane_map[$n].

Let the ad_xcvrcon handle the ADI JESD204 link layer cores. The function
will detect the JESD204 core vendor and connect the appropriate signals
based on it. This means it can still be used with the Xilinx JESD204 core
as well.

When trying to use ad_cpu_interconnect to connect to a AXI interface that
is a outer port of a hierarchy this will fail at the moment as it kind find
the matching clock and reset signals.
Add support for traversing into the hierarchy and find the final target AXI
port inside the hierarchy. Then find the matching clock and reset and
traverse them back the corresponding hierarchy outer ports.

In case of axi_interconnects, when just one slave and master interface is
active, the 'Interconnect Optimization Strategy' is disabled. So this
parameter should be set just if there is more than one slave interface.
Only enable bitstream compression only if both the
ADI_NO_BITSTREAM_COMPRESSION environment and TCL variable are not set.

Enabling bitstream compression reduces the size of the generated bitstream.
This means on one hand it will consume less storage, which is especially
useful for the BOOT partition of the ADI images where we store BOOT.BIN
files for all supported platforms.
On the other hand a smaller bitstream is faster to load from the storage
medium and it is also faster to program to the FPGA. So it reduces the
overall boot time as well.
The only downside of bitstream compression is that the bitstream size is no
longer constant, but depends on the actual design and resource utilization.
This will not work with bootloaders that expect a fixed size.
When building a bitstream using the tcl scripts bitstream compression can
be disabled by setting the ADI_NO_BITSTREAM_COMPRESSION environment
variable.
Initial tests show a reduction of a round 50% in size for most ADI
projects.
