[PATCH 5.10 420/575] powerpc: Refactor is_kvm_guest() declaration to new header

[Greg Kroah-Hartman]

From: Srikar Dronamraju <srikar@xxxxxxxxxxxxxxxxxx>

[ Upstream commit 92cc6bf01c7f4c5cfefd1963985c0064687ebeda ]

Only code/declaration movement, in anticipation of doing a KVM-aware
vcpu_is_preempted(). No additional changes.
