Documentation: dt: kona-timer: Add clocks property
The frequency for the Kona timer can either be specified through the device tree or determined by checking the rate of the clock specified in the device tree. Update the documentation to reflect both ways. Signed-off-by: Tim Kryger <tim.kryger@linaro.org> Reviewed-by: Matt Porter <matt.porter@linaro.org> Signed-off-by: Christian Daudt <bcm@fixthebug.org>
