Hello!
I started playing with PowerPC e500 architecture, it is something really

powerpc/pci: Make pcibios_make_OF_bus_map() static
powerpc/pci: Hide pci_create_OF_bus_map

Make just one .setup_arch and one .init_IRQ callback implementation for all
P2020 board code. This deduplicate repeated and same code.

This moves machine descriptions and all related code for all P2020 boards
into new p2020.c source file. This is preparation for code deduplication
and providing one unified machine description for all P2020 boards.

Kernel during booting correctly detects P2020 and prints:

powerpc/85xx: Mark mpc85xx_rdb_pic_init() as static

powerpc/85xx: p2020: Move all P2020 machine descriptions
CONFIG_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.

CONFIG_PPC_EARLY_DEBUG_16550_STRIDE.
With this change it is possible to debug powerpc machine descriptor code.
For example this early debugging code can print on serial console also
"No suitable machine description found" error which is done before
legacy_serial.c code.

ic unified support for boards with P2020
processors, there is no need to have this "hack" in turris1x.dts file.
So remove incorrect "fsl,P2020RDB-PC" compatible string from turris1x.dts.
