[PATCH 2/5] arm64: mm: remove unused __cpu_uses_extended_idmap[_level()]

[Ard Biesheuvel]

These routines lost all existing users during the latest merge window so
we can remove them. This avoids the need to fix them in the context of
fixing a regression related to the ID map on 52-bit VA kernels.
