ARM: multiplatform: always pick one CPU type
PATCH 1/1 ARM: multiplatform: always pick one CPU type
With the new default platform code, we can always boot using DT without requiring a board file, but we cannot build a kernel unless we select at least one CPU core, which breaks some "randconfig" builds.
This adapts the ARCH_MULTI_V4T and ARCH_MULTI_V5 options so we always default to a common CPU core if no platform was enabled that picks something else. The default we pick for ARMv4T is ARM920T, while for ARMv5 we pick ARM926T.
