From: Daniel Lezcano <daniel.lezc...@linaro.org>
With one function handling the idle state and a single variable,
the usage of the davinci_ops is overkill.
This patch removes these ops and simplify the code.
Furthermore, the 'driver_data' field is no longer used, we have
1 of the 3 remaining user of this field removed.
