audio: eap: Add support for custom NXP config parameters

In order to have a meaningful processing we need to use custom NXP
configuration parameters. We cannot include the configuration files
into SOF repo because of the license.

Users need to clone the https://github.com/nxp-mcuxpresso/EAP repo which
contains the library binary and the configuration files.
