arm64: mvebu: Rename db-88f7040 files to armada-8k

This moves some of the Armada DB-88F7040 board specific files to a more
generic name: armada-8k. This is in preparation for the Armada-8k
support which will be added soon. And since both platforms share
most devices, lets also share most source files to not duplicate
the code here.
