This has been discussed before, and what we have chosen to do is to
just have a multi_v7_defconfig that all these platforms are enabled on
but with LPAE off.

Instead, what we do when building (and on our build/boot builders) is
to take multi_v7 and provide the snippet that turns on ARM_LPAE at
that time.
