clk: mvebu: initial support for AP806 clocks

Hello,

The following set of patches add initial support for the main clocks found in the AP806 hardware block, which is the central block used in the newest Marvell 7K and 8K 64-bits processors.

Two new drivers are added, one for the so-called "core" clocks and one for the "ring" clocks. The latter are child clocks from one of the core clocks. The "core" clocks are fixed rate clocks, but their rate is calculated from values in the Sample At Reset register.

Changes since v1:
- Introduce a minimal DT binding for the AP806 DFX Server register area, and make the clock DT nodes child nodes of the DFX server node. Implementation-wise, we use the simple-mfd/syscon mechanism.
- Separate the DT binding documentation into its own patches.

Thanks!

Thomas
