x86/mm/hotplug: Put kernel_physical_mapping_remove() declaration in
CONFIG_MEMORY_HOTREMOVE
kernel_physical_mapping_remove() is only called by
arch_remove_memory() in init_64.c, which is enclosed in
CONFIG_MEMORY_HOTREMOVE. So when we don't configure
CONFIG_MEMORY_HOTREMOVE, the compiler will give a warning:
warning: ‘kernel_physical_mapping_remove’ defined but not used
So put kernel_physical_mapping_remove() in
CONFIG_MEMORY_HOTREMOVE.
