Subject: [PATCH v2 15/16] ARM: tegra: Add entries for cpufreq on Tegra124

The Tegra124 cpufreq driver relies on certain clocks being present
in the /cpus/cpu@0 node.

Signed-off-by: Tuomas Tynkkynen <ttynkkynen@...dia.com>

v2 changes:
    - The clock-latency property was added, as cpufreq-cpu0 wants that
