[PATCH v2] ARM: Kconfig: Do not force selection of ARCH_VEXPRESS by ARCH_MULTI_V7

From: Fabio Estevam <fabio.estevam at freescale.com>
When building a kernel using imx_v6_v7_defconfig, it is not possible to unselect
ARCH_VEXPRESS due to the fact that it is automatically selected by ARCH_MULTI_V7.
This is not good when someone wants to create a minimal kernel build, so let
multi_v7_defconfig select ARCH_VEXPRESS instead.
Also avoid build breakage when randconfig selects no platform.

Changes since v1:
- Avoid build breakage on randconfig for the case that no platform is selected.
