axi_adrv9001: Add status bit for Tx clocking

If Tx source synchronous clock is not routed through clock capable pins
the interface and driving logic must run on the Rx interface clock.
This introduces a dependency, Rx interface must be bring up before the
Tx. In this mode a Tx only operation is not possible.

This is done through a synthesis parameter.
Expose this parameter to the software so it can query if the limitations
exists in the implementation.
