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.
