Marvell: Reorganize file structure
In edk2-platforms it is expected to provide a separation between
SoC and boards files in 'Silicon' and 'Platform' directories
accordingly.
This patch aligns Marvell code to this requirement with no functional
changes in the actual source files, unless required due to modified
paths. Change the supported board's files names to proper Armada70x0Db.
Also rename 'Armada' directory to 'Armada7k8k' in order to properly
refer to the SoC family and prevent confusion in future, when
adding new Armada machines. On the occasion add ARM copyright,
which was wrongly missing in the dsc.inc file.
