platform: ariane: Move ariane platform from fpga to generic

Browse Source 
The Ariane framework has a generic PMU that is not used by OpenSBI.
Due to OpenSBI’s build system we cannot directly reuse the generic
platform functions, so move the Ariane platform to generic. Also due
to the generic platform is where new features are added.
