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.

Changes in v2:
- Use H3 DE2 CCU compatible as it's discovered that H3 and A83T DE2 CCU are
  not equal.

Could you split that patch in half, with the common part in one patch,
and the H3 part in a second one?

This is a nightmare to merge otherwise.

Thanks!
