This series of changes enables the use device tree based sysconfig
data for ti-sysc driver. As we already have SmartReflex data configured,
we use that as the first driver to enable. To do that in a way where
SmartReflex is not probed twice, we need to prepare the SmartReflex
driver before flipping dts data on for it in the last patch of the
series.

To avoid regressions, we are checking the passed dts data against
existing platform data since we still have it available. Then after the
dts files are converted, we can simply drop the related platform data
at some point in the future.
