There can be a rather high latency between the last byte of a burst has been send and the time the response for the burst is received. Running at high samplerates this can cause the internal DMA store and forward FIFO to fill up and subsequently stall the DMA pipeline and drop samples. To better cope with the situation double the size of the internal FIFO. Also increase the clock of the AXI bus to be able to accommodate a samplerate of 310MHz.

The axi_dmac supports native AXI3, there is no need to add a interconnect
for protocol conversion between it and the HP port.

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.
