The device has a requirement to operate in a 1Mhz to 2Mhz range. So the
driver is using a clk_round_rate() to get the closest rate supported and
sets it using a clk_set_rate().

I am fine if this needs to be moved to platform-specific code, but I
wasn't quite sure this needs to be done in clock framework as was
suggested.
