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. (in followup patches)
