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.
