arm64: mmu: Make __cpu_replace_ttbr1() out of line

__cpu_replace_ttbr1() is a static inline, and so it gets instantiated
wherever it is used. This is not really necessary, as it is never called
on a hot path. It also has the unfortunate side effect that the symbol
idmap_cpu_replace_ttbr1 may never be referenced from kCFI enabled C
code, and this means the type id symbol may not exist either.  This will
result in a build error once we start referring to this symbol from asm
code as well. (Note that this problem only occurs when CnP, KAsan and
suspend/resume are all disabled in the Kconfig but that is a valid
config, if unusual).

So let's just move it out of line so all callers will share the same
implementation, which will reference idmap_cpu_replace_ttbr1
unconditionally.
