clk: nodrv: Add a determine_rate hook
The nodrv clock implements a mux with a set_parent hook, but doesn't
provide a determine_rate implementation.
Even though it's a mock clock and the missing function is harmless,
we'll start to require a determine_rate implementation when set_parent
is set, so let's fill it.
