hw/arm/virt: tcg: adjust MPIDR like KVM
KVM adjusts the MPIDR of guest vcpus based on the architecture of
the host, 32-bit vs. 64-bit, and, for 64-bit, also on the type of
GIC the guest is using. To be consistent and improve SGI efficiency
we make the same adjustments for TCG as 64-bit KVM hosts. We neglect
to add consistency with 32-bit KVM hosts, as that would reduce SGI
efficiency and KVM is expected to change.
As MPIDR is a system register, and thus guest visible, we only make
adjustments for current and later versioned machines.
