[PATCH v2 0/8] powerpc/85xx: p2020: Create one unified machine description

[Pali Rohár]

This patch series unifies all P2020 boards and machine descriptions into
one generic unified P2020 machine description. With this generic machine
description, kernel can boot on any P2020-based board with correct DTS
file.

Tested on CZ.NIC Turris 1.1 board with has Freescale P2020 processor.
Kernel during booting correctly detects P2020 and prints:
[    0.000000] Using Freescale P2020 machine description

Changes in v2:
* Added patch "p2020: Move i8259 code into own function" (separated from the next one)
* Renamed CONFIG_P2020 to CONFIG_PPC_P2020
* Fixed descriptions
