fix: serialize powering on secondary CPUs This patch provides a temporary workaround for the following issue seen with a notifications test in SPM test suite. ERROR: Unexpected affinity info state. PANIC in EL3. The reason for assertion fail in warmboot entrypath for a secondary CPU needs further investigation but we believe it is possibly related to the more common issue in the PSCI library as described here [1] In order to increase the time between cache line invalidations, TFTF brings secondary CPUs online one after the other.
