In some cases (GTX2) the transceiver may gate the out_clk when it is in
reset. This will stop the clock generators from getting a clock prior
removing the reset of the XCVR. The XCVR has a requirement of running
user clock while removing the reset. The correct sequence must be :
Enable device clocks (user clock)
Remove the reset from the XCVR
The process ad_xcvrcon has a device_clk attribute which can be used to
connect a custom device clock to the XCVR. Fix the proc call so we can
simplify the block design script.
Use the new util_cpack2 and util_upack2 cores. They have lower utilization
that the old util_cpack and util_upack cores.

The TX side runs on QPLL, and the RX and RX_OS runs on CPLL by default.
The OUTCLK frequency is the same as the REFCLK.
The main reason of this modification is that the links should come up
without any DPR access, after power up, using the default reference clock
configuration (122.88 MHz).
Convert the ADRV9371 project to the ADI JESD204 link layer cores. The
change is very straight forward, but a matching change on the software side
is required.

Because the S_AXI interface of the axi_adxcvr core was infered
using the process adi_ip_properties, the interface address range
has changed from 4k to 64k. As a result, all the addresses of
the axi_adxcvr cores were changed and realigned.
If the VDMA and the GTs AXI are connected to the same HP port, the
HDMI won't work on full resolution (1080p). Care should be taken, this can
affect the receive and observation paths (both are connected to HP2).
