clk: Clarify clk_get_rate() expectations
As shown by a number of clock users already, clk_get_rate() can be
called whether or not the clock is enabled.
Similarly, a number of clock drivers will return a rate of 0 whenever
the rate cannot be figured out.
Since it was a bit ambiguous before, let's make it clear in the
clk_get_rate() documentation.
