arm64: mvebu: Fix A8K memory mapping and add documentation

Fix the MMU mapping for A8K device family:
 - Separate A7K and A8K memory mappings
 - Fix memory regions by including IO mapping for all
   3 PCIe interfaces existing on each connected CP110 controller
Add A8K memory mapping documentation with all regions
configured by Marvell ATF.

+		     Memory Layout on Armada-8k SoC's
+		     ================================
+
+The below desribes the physical memory layout for Marvell's Armada-8k SoC's.
+
+This assumes that the SoC includes Dual CP configuration, in case the flavor is using
+a single CP configuration, then all secondary-CP mappings are invalid.
+
+All "Reserved" areas below, are kept for future usage.
