arm64: kernel: Don't rely on objcopy to make code under pi/ __init

Browse source

We will add some code under pi/ that contains global variables that
should not end up in __initdata, as they will not be writable via the
initial ID map. So only rely on objcopy for making the libfdt code
__init, and use explicit annotations for the rest.
