ARM: dts: dra7: Set cpufreq transition latency value
Without clock-latency initialization, default value of (2^32 -1)
is taken. Because of the too long transition latency, ondemand
governor fails and the cpufreq governor fallback to performance
governor.
With this change, ondemand governor can be enabled by default for DRA7.
clock-latency value referenced from omap5 (TBD: to be instrumented and
use the actual value at later point of time)
