Kirill A. Shutemov 6657fca06e x86/mm: Allow to boot without LA57 if CONFIG_X86_5LEVEL=y 
All pieces of the puzzle are in place and we can now allow to boot with
CONFIG_X86_5LEVEL=y on a machine without LA57 support.

Kernel will detect that LA57 is missing and fold p4d at runtime.

Update the documentation and the Kconfig option description to reflect the
change.
