The DE2 in H3/H5 has a clock control unit in it, and the behavior is
slightly different between H3 and H5.
Add the common parts in H3/H5 DTSI, and add the compatible string in H3
DTSI.
The compatible string of H5 DE2 CCU will be added in a separated patch.

Sorry, this compatible is wrong.
Please wait for my new version of this patchset to add a
allwinner,sun8i-h3-de2-clk and use it.
(A83T doesn't have DE mod clk, but H3 has)
