Subject: [PATCH 16/25] clocksource/drivers/tegra: Restore timer rate on Tegra210

From: Dmitry Osipenko <digetx@...il.com>

The clocksource rate is initialized only for the first per-CPU clocksource
and then that rate shall be replicated for the rest of clocksource's
because they are initialized manually in the code.

Fixes: 3be2a85a0b61 ("clocksource/drivers/tegra: Support per-CPU timers on all Tegra's")
