driver/intel/fsp2_0: Allow function to run serially on all APs

EFI_PEI_MP_SERVICES_STARTUP_ALL_APS passes in a boolean flag singlethread
which indicates whether the work should be scheduled in a serially on all APs
or in parallel. Current implementationof this function mp_startup_all_aps
always schedules work in parallel on all APs. This implementation ensures
mp_startup_all_aps honors to run serialized request.
