ARM: Kconfig: move platform selection into its own Kconfig file
Mostly just for better organization for now. This matches what is done on some other platforms including ARM64. This also lets us start to reduce the number of mach- directories that only exist to store the platform selection. Start with "Platform selection" and ARCH_VIRT.
