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.
