When using non-broadcast access to the GT DRP registers lane filtering is
done on both sides. The ready and data signals are filtered in the in the
axi_adxcvr module and the enable signal is filtered in the util_adxcvr
module. This works fine as long as both sides use the same transceiver IDs.
E.g. channel 0 of the axi_adxcvr module is connected to channel 0 of the
util_adxcvr module.
But this is not always the case. E.g. on the ADRV9371 platform there are
two RX axi_adxcvr modules (RX and RX_OS) connected to the same util_adxcvr.
The first axi_adxcvr uses lane 0 and 1 of the util_adxcvr, the second uses
lane 2 and 3.
Non-broadcast access for the first RX axi_adxcvr module works fine, but
always generates a timeout for the second axi_adxcvr module. This is
because lane 0/1 of the axi_adxcvr module is connected to lane 2/3 of the
util_adxcvr and when ID based filtering is done both can't match at the
same time.
To avoid this perform the filtering for all the signals in the axi_adxcvr
module. This makes sure that the same base ID is used.
This also removes the sel signal from the transceiver interfaces since it
is no longer used on the util_adxcvr side.

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.

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.
