modularization: boot component -- move functions Boot component prepares the very basic platform boot env. It finally call into platform initilization entries: - bsp_boot_init & cpu_secondary_init for start up - or restore_s3_context for wakeup this patch move functions for AP trampoline into trampoline.c from reloc.c Tracked-On: #1842 Signed-off-by: Jason Chen CJ <jason.cj.chen@intel.com>

hv: drop the temperory stack for AP startup By switching AP wakeup from broadcast to one by one, we could set correct stack for each AP and drop the temp stack used during AP boot. Tracked-On: #2034 Signed-off-by: Yin Fengwei <fengwei.yin@intel.com> Acked-by: Anthony Xu <anthony.xu@intel.com>
