From: Baruch Siach <baruch@tkos.co.il> Add compatible strings for AP806 and CP110 that are part of the Armada 8k/7k line of SoCs. Add a note on the differences in the size of the control area in different bindings. This is an existing difference between the Armada 375 binding and the other boards already supported. The new AP806 and CP110 bindings are similar to the existing Armada 375 in this regard.
