x86, realmode: Separate real_mode reserve and setup
After we switch to use #PF handler help to set page table, init_level4_pgt
will only have entries set after init_mem_mapping().
We need to move copying init_level4_pgt to trampoline_pgd after that.
So split reserve and setup, and move the setup after init_mem_mapping()
