[U-Boot] [PATCH 4/4] dm: omap-timer: Update clock rate only if not populated

[Lokesh Vutla]

timer_pre_probe() tries to populate the clock rate from DT. omap
timer driver tries to overwrite this value irrespective of the value
populated fro DT. So update this value only when DT doesn't populate
the clock rate.
