Since 617276307cd4c ("ARM: vexpress: convert to multi-platform") it has been impossible to select ARCH_VEXPRESS without ARCH_MULTIPLATFORM. ARCH_MULTIPLATFORM doesn't make sense for NOMMU targets, not least because of the need to hard-code the memory map. However, it should still be possible to run NOMMU kernels on top of the Versatile Express by selecting it as the only platform. This patch creates a shim ARCH_VEXPRESS_NOMMU config option in the 'choice' for "ARM system type" to make this possible again.
