[PATCH 4/6] rtla/osnoise_top: Pass the params to the usage function

[Daniel Bristot de Oliveira <bristot@xxxxxxxxxx>]

In preparation to the hwnoise tool, pass the osnoise top params to the
usage function so it can be adapted according to the mode of the tool.

Also make it static, as it is only used in this file.
