A KVM-only build won't be able to run M-profile cpus.

Only enable the following ARMv7 M-Profile CPUs when TCG is available:

  - Cortex-M0
  - Cortex-M3
  - Cortex-M4
  - Cortex-M33

We don't need to enforce CONFIG_ARM_V7M in default-configs because
all machines using a Cortex-M are already explicitly selected.
