arm64: Move the initial kernel stack out of the init_pagetables section
init_pagetables is mapped into the segment containing the BSS, but does not get zeroed by locore. It is used for bootstrap page table pages. It happens that the bootstrap kernel stack is also placed in that section, but there's no reason it shouldn't live in the BSS, so move it there. No functional change intended.
