+Add refclock and tcxoclock as clock providers in WiLink.  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.
