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
change 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.
