Earlier timer driver needed a clock-frequency property in compatible device-tree nodes. Another way is to reference a clock via a phandle.
So now timer_pre_probe tries to get clock by reference through device tree. In case it is impossible to get clock device through the reference, clock-frequency property of the timer node is read to provide backward compatibility.
