Commit 78869f0f0552 ("arm64: Extract parts of el2_setup into a macro")
reorganized el2 setup in such way that virtual cpu id registers set
only in nVHE, yet they used (and need) to be set irrespective VHE
support.

Changelog
v1 -> v2
- Drop the reference to 32bit guests from commit message (per Marc)
There is no upstream fix since issue went away due to code there has
been reworked in 5.12: nVHE comes first, so virtual cpu id register
are always set.
Maintainers, please, Ack.
