Chen-Yu Tsai e7e7e0d7be clocksource/drivers/sun5i: Fail gracefully when clock rate is unavailable
If the clock tree is not fully populated when the timer-sun5i init code
is called, attempts to get the clock rate for the timer would fail and
return 0.

Make the init code for both clock events and clocksource check the
returned clock rate and fail gracefully if the result is 0, instead of
causing a divide by 0 exception later on.
