[23/26] KVM: arm64: Move and consolidate "public" functions in asm/kvm_host.h

Commit Message

Sean Christopherson Sept. 16, 2023, 12:31 a.m. UTC

Move a variety of "public" symbols in arm64's kvm_host.h, i.e. symbols and
functions that are used by non-KVM code, towards the top of the header.
This will allow hiding the "private" code in kvm_host.h, i.e. the stuff
that is intended to be KVM-internal, with a minimal amount of #ifdeffery.
