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.

Fixes:
