These clocks are not accesible outside the WiLink module, but they are registered in the clock framework anyway. Only the WiLink chip consumes these clocks. In theory, the WiLink chip could be connected to external clocks instead of using these internal clocks, so make the clock consumer code generic enough. If external clocks are used, then the internal clock device tree nodes are not necessary, but the external ones must be specified.
