[PATCH-for-9.0? v2 3/8] hw/clock: Pass optional &bool argument to clock_set_ns()

[Philippe Mathieu-Daudé]

Pass optional &bool argument to clock_set_ns().
Since all callers ignore the return value, have
them use NULL.

 To enforce that the clock is wired up by the board code, you can
 call ``clock_has_source()`` in your device's realize method:
