powerpc/mm: Fix section mismatch warning in stop_machine_change_mapping()
Fix the warning messages for stop_machine_change_mapping(), and a number
of other affected functions in its call chain.
All modified functions are under CONFIG_MEMORY_HOTPLUG, so __meminit
is okay (keeps them / does not discard them).
Boot-tested on powernv/power9/radix-mmu and pseries/power8/hash-mmu.
$ make -j$(nproc) CONFIG_DEBUG_SECTION_MISMATCH=y vmlinux

WARNING: vmlinux.o(.text+0x6b130): Section mismatch in reference from the function stop_machine_change_mapping() to the function .meminit.text:create_physical_mapping()
The function stop_machine_change_mapping() references
the function __meminit create_physical_mapping().
This is often because stop_machine_change_mapping lacks a __meminit
annotation or the annotation of create_physical_mapping is wrong.
