feat(plat/nxp/ls1043ardb): add ls1043ardb board support

The LS1043A reference design board (RDB) is a computing, evaluation,
and development platform that supports the Layerscape LS1043A
architecture processor.

The old implementation in tf-a (plat/layerscape/board/ls1043/) is removed,
and this patch is adding it back, it is using the unified software
component and architecture with all the other Layerscape platforms.
