This is a really long list. I don't think all of them need to be exposed,
especially the intermediate ones in TOPCKGEN. In such cases the not-to-be-
exposed clock indices could be moved to a header file in the driver directory,
or simply left out.

The Allwinner/sunxi-ng drivers do the former while the Rockchip drivers do
the latter. The Mediatek clock drivers are more similar in structure and
design to the Rockchip ones.
