[lib][sm] Create all sm threads on the main CPU If we sleep during boot on the main CPU while holding the vmm_lock mutex before sm_secondary_init calls thread_create which blocks on that mutex, we hit a deadlock where all secondary CPUs are blocked on vmm_lock while the NS OS gets stuck trying to schedule those CPUs over the main one. This fixes the deadlock by creating the threads on the main CPU. Bug: 217580763 Change-Id: Ie3d24655c8ad7394f35c9e5f258c3e5bb1523296
