The low-level relocate() function enables mmu and relocates execution to link-time addresses. We rename relocate() function to relocate_enable_mmu() function which is more informative. Also, the relocate_enable_mmu() function will be used in the resume path when a CPU wakes-up from a non-retentive suspend so we make it global symbol.
