x86: introduce init_memory_mapping for 32bit #1
... so can we use mem below max_low_pfn earlier. this allows us to move several functions more early instead of waiting to after paging_init. That includes moving relocate_initrd() earlier in the bootup, and kva related early setup done in initmem_init.
