The generic ARM TWD code has recently gained support for looking up the
clock from DT. Adding the appropriate clocks property allows the driver
to successfully register the clock event device.

Note that the binding documentation says that the twd clock is 132 on
Tegra20, but according to drivers/clk/tegra/clk-tegra20.c it is in fact
130. The patch doesn't update the binding documentation because some
other offsets are probably also wrong and I didn't have the time to go
through all of them.
