powerpc: drop MPC85xx_CDS platform support
The MPC8541/8548/8555 Configurable Development System (CDS) were the
vehicle used to provide evaluation of the 1st e500-v2 CPUs around 2007.
Similar to the earlier MPC83xx-MDS systems we removed, the "brains"
exist on a PCI-X card, but additional connectors exist to the right of
the PCI-X slot, two structural metal pins are used to provide stability
in a vertical ATX mounting, and the CPU is now on a daughter-card vs. a
clamped down BGA.
Given the extra complexity and risk of connector damage, the 8548CDS
I had access to came pre-assembled in a basic white Antec case common
for that era, and I'm inclined to assume that was the default.
Power was typical "Pentium4" 2005 ATX - the main 20 pin connector went
to the PCI ATX form factor backplane, and the 4 pin black/yellow went
to the CPU card.
Like previous evaluation boards, they attempted to provide break-out
connectors for as many features as possible, and that made for a fairly
complex looking system.
In any case, these are over 15 years old, and fairly complex systems,
originally made for a small group of industry related people, and made
for use where quiet fan operation wasn't important. Given that, it
makes sense to remove support from them in 2023.

powerpc/85xx: p2020: Enable boards by new config option CONFIG_PPC_P2020
Generic unified P2020 machine description which supports all P2020-based
boards is now in separate file p2020.c. So create a separate config option
CONFIG_PPC_P2020 for it.
Previously machine descriptions for P2020 boards were enabled by
CONFIG_MPC85xx_DS or CONFIG_MPC85xx_RDB option. So set CONFIG_PPC_P2020 to
be enabled by default when one of those option is enabled.
This allows to compile support for P2020 boards without need to have
enabled support for older mpc85xx boards. And to compile kernel for old
mpc85xx boards without having enabled support for new P2020 boards.
