CBMEM: Clarify CBMEM_TOP_BACKUP function usage
The deprecated LATE_CBMEM_INIT function is renamed:
set_top_of_ram -> set_late_cbmem_top
Obscure term top_of_ram is replaced:
backup_top_of_ram -> backup_top_of_low_cacheable
get_top_of_ram -> restore_top_of_low_cacheable
New function that always resolves to CBMEM top boundary, with
or without SMM, is named restore_cbmem_top().
