[PATCH] ARM: cpu: allow selecting CPU_V7/CPU_V8 directly

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We currently lack a way to build a barebox EFI payload on ARM without
enabling some other subarchitecture. As CONFIG_EFI_PAYLOAD has a global
effect and adds EFI stubs to all enabled board, an EFI subarchitecture
doesn't fit into our current model.

Instead, let's make it possible to enable either CONFIG_CPU_V8 or
CONFIG_CPU_V7 directly.
