This is incorrect in 10% of the cases. Rather than generating yet another set of topology files, this patch adds a kernel module parameter to override the topology value. In hindsight, we should never have allowed mclks to be specified in topology, this is a hardware-level information that should not have been visible in the topology. Future patches will try to set this value automagically, e.g. by parsing the NHLT content.
