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.

Property 'board' is deprecated for object type 'project', 'board_part' is used. Update the 'board_part' property names for all Xilinx development boards.
Add .gitattributes file which sets up the eol encoding handling. This will
make sure that we get a uniform eol encoding across different operating
systems.

The scripts generating the projects files typically only work correctly with
one specific version of Vivado. If a incorrect version is used the script
may fail at some point with a cryptic error message or may not fail but
create a bitstream that is not working as expected, e.g. unconnected
signals, etc. This patch adds a version check to adi_project_create that
will error out early on stating that the wrong version of Vivado was used
and which is the right version to use.
By default the required version will be the version that is required by the
common scripts. Individual projects can overwrite the required version by
setting the REQUIRED_VIVADO_VERSION variable to the required version or can
bypass the version check completely by setting the IGNORE_VERSION_CHECK
variable to 1.
Callers of the script can also disable the version check by setting the
ADI_IGNORE_VERSION_CHECK environment variable.

- Change implementation strategy to Performance Explore.
At some projects, this could prevent timing issues, it not
increase the overall implementation time in a dramatic way.
The FMCOMMS1 meets timing on ZED/ZC702 only if the phys_opt_design step
is part of the implmentation flow, with the Explore argument.
"This step performs physical optimizations such as timing-driven
replicaiton of high fanouts nets to improve timing results"
