Add ENV_STAGE_SUPPORTS_SMP to clean up spinlock stubs

Browse Source 
CONFIG(SMP) was an invalid condition to use in cases where one
stage requires spinlocks and another one does not. The
stage not requiring spinlock still required <smp/spinlock.h>
to be implemented with no-op stubs.

This reverts commit 037ee4b556
