Subject: [PATCH 097/115] target/i386: move accel_cpu_instance_init to
 .instance_init

RH-Author: Paolo Bonzini <pbonzini@redhat.com>
RH-MergeRequest: 391: TDX support, including attestation and device assignment

RH-Commit: [97/115] b2725f7b55754f8ec6a54428eb1d70c588eb09ef (bonzini/rhel-qemu-kvm)

With the reordering of instance_post_init callbacks that is new in 10.1
accel_cpu_instance_init must execute in .instance_init as is already
the case for RISC-V.  Otherwise, for example, setting the vendor
property is broken when using KVM or Hypervisor.framework, because
KVM sets it *after* the user's value is set by DeviceState's
intance_post_init callback.
