[PATCH v3 26/60] arm64: Move feature overrides into the BSS section

[Ard Biesheuvel]

In order to allow the CPU feature override detection code to run even
earlier, move the feature override global variables into BSS, which is
the only part of the static kernel image that is mapped read-write in
the initial ID map.
