Add a new configuration option that will be used for KVM SPE emulation.
CONFIG_KVM_ARM_SPE depends on the SPE driver being builtin because:
1. The cpumask of physical CPUs that support SPE will be used by KVM to
emulate SPE on heterogeneous systems.
2. KVM will rely on the SPE driver enabling the SPE interrupt at the GIC
level.
