modularization: boot component -- move functions

Browse Source 
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
