Add support for the clock unit found in the A23. Due to the similarities
with the A33, it also shares its clock IDs to allow sharing the DTSI.Signed-off-by: Maxime Ripard

This commit introduces the clocks found in the Allwinner A33 CCU.
Since this SoC is very similar to the A23, and we share a significant share
of the DTSI, the clock IDs that are going to be used will also be shared
with the A23, hence the name of the various header files.Signed-off-by: Maxime Ripard

Some clocks in the Allwinner SoCs clocks unit are just muxes.
However, those muxes might also be found in some other complicated clocks
that would benefit from the code in there to deal with "advanced" features,
like pre-dividers.Introduce a set of helpers to reduce the code duplication in such cases.

Some clocks in the Allwinner SoCs clocks unit are just simple gates. Add
support for those clocks.Since it's a feature that can also be found in more complex clocks, provide
a bunch of helpers that can be reused later on.Signed-off-by: Maxime Ripard

output rate you can choose from.Add a small library to deal with those clocks.
