[PATCH v5 27/39] arm64/kernel: Move 'nokaslr' parsing out of early idreg code

[Ard Biesheuvel]

From: Ard Biesheuvel <ardb at kernel.org>

Parsing and ignoring 'nokaslr' can be done from anywhere, except from
the code that runs very early and is therefore built with limitations on
the kind of relocations it is permitted to use.

So move it to a source file that is part of the ordinary kernel build.
