timer: add OF_PLATDATA support for timer-uclass
The timer-uclass depends on full OF_CONTROL through its interrogation
of /chosen and the code to determine the clock-frequency.
For the OF_PLATDATA case, these code-paths are disabled and it becomes
the timer driver's responsibility to correctly set the clock-frequency
in the uclass priv-data.
