arm64: Revert "mm: provide idmap pointer to cpu_replace_ttbr1()"
This reverts commit 1682c45b920643c, which is no longer needed now that
we create the permanent kernel mapping directly during early boot.
This is a RINO (revert in name only) given that some of the code has
moved around, but the changes are straight-forward.
