To allow regression build testing of multi v5 systems, add a
multi_v5_defconfig, similar to the multi_v7_defconfig. This is based
on kirkwood_defconfig, but with a few other boards added which claim
to be MULTI_v5.

Should we disable lowlevel debug for multi-* config?

Yes, definitely.

On a related note, I'd like to add a CONFIG_BROKEN_MULTIPLATFORM Kconfig
symbol and make all options depend on that which will result in a kernel
that is not actually multiplatform but can only run on a subset of the
platforms you can enable together. Aside from DEBUG_LL, this would
include XIP_KERNEL, !MMU, !ARM_PATCH_PHYS_VIRT, ZBOOT_ROM, !AUTO_ZRELADDR
and possibly more. A multi_*_defconfig by definition must not enable
BROKEN_MULTIPLATFORM, but there can be good reasons for individual
configurations to enable that when you want to build for a specific
system that happens to be part of ARCH_MULTIPLATFORM.
