Local timer clock is sourced from the CPU clock and hence changes along with CPU clock. These per CPU local timers are used as clock-events, so they need to be reconfigured on CPU frequency as part of CPUfreq governor. Newly introduced clockevents_reconfigure() needs to know the TWD clock-rate. Provide a clock-node to make clk_get_rate() work for TWD.
