Merge branch kvm-arm64/6.6/generic-vcpu into kvmarm-master/next

* kvm-arm64/6.6/generic-vcpu:
  : .
  : Cleanup the obsolete vcpu target abstraction, courtesy of Oliver.
  : From the cover letter:
  :
  : "kvm_vcpu_init::target is quite useless at this point. We don't do any
  : uarch-specific emulation in the first place, and require userspace
  : select the 'generic' vCPU target on all but a few implementations.
  :
  : Small series to (1) clean up usage of the target value in the kernel and
  : (2) switch to the 'generic' target on implementations that previously
  : had their own target values. The implementation-specific values are
  : still tolerated, though, to avoid UAPI breakage."
  : .
  KVM: arm64: Always return generic v8 as the preferred target
  KVM: arm64: Replace vCPU target with a configuration flag
  KVM: arm64: Remove pointless check for changed init target
  KVM: arm64: Delete pointless switch statement in kvm_reset_vcpu()
