From: Pali Rohár <p...@kernel.org>
This moves machine descriptions and all related code for all P2020 boards
into new p2020.c source file.
This is preparation for code de-duplication and
providing one unified machine description for all P2020 boards. In
follow-up patches would be copied functions refactored and simplified to be
specific just for P2020 boards.

[chleroy: Split in two patches: one for DS, one for RDB and keep helpers out]
