arch/Config.in.arm: re-organize MMU selection
So far, all ARM cores were selecting BR2_ARCH_HAS_MMU_OPTIONAL, except no-MMU cores which were selecting nothing. In practice, MMU-capable ARM cores are always used with their MMU enabled, so it doesn't make sense to support the use case of not using the MMU on such cores. Consequently, to simplify things, we group the MMU handling in the BR2_ARM_CPU_ARM* options: BR2_ARM_CPU_ARMV4, BR2_ARM_CPU_ARMV5, BR2_ARM_CPU_ARMV6, BR2_ARM_CPU_ARMV7A, BR2_ARM_CPU_ARMV8A all select BR2_ARCH_HAS_MMU_MANDATORY, while BR2_ARM_CPU_ARMV7M continues to select nothing, indicating that there is no MMU available at all.
