[PATCH v4 11/17] powerpc/85xx: p2020: Move all P2020 RDB machine descriptions to p2020.c

[Christophe Leroy]

From: Pali Rohár <pali@xxxxxxxxxx>

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]
