Hi All,

This patch series support enabling HV and PR KVM together in the same kernel. We
extend machine property with new property "kvm_type". A value of "HV" will force HV
KVM and "PR" PR KVM. If we don't specify kvm_type we will select the fastest KVM mode.
ie, HV if that is supported otherwise PR.

With Qemu command line having

 -machine pseries,accel=kvm,kvm_type=HV

[root@llmp24l02 qemu]# bash ../qemu
failed to initialize KVM: Invalid argument
[root@llmp24l02 qemu]# modprobe kvm-pr
[root@llmp24l02 qemu]# bash ../qemu
failed to initialize KVM: Invalid argument
[root@llmp24l02 qemu]# modprobe  kvm-hv
[root@llmp24l02 qemu]# bash ../qemu

now with

 -machine pseries,accel=kvm,kvm_type=PR

[root@llmp24l02 qemu]# rmmod kvm-pr
[root@llmp24l02 qemu]# bash ../qemu
failed to initialize KVM: Invalid argument
[root@llmp24l02 qemu]#
[root@llmp24l02 qemu]# modprobe kvm-pr
[root@llmp24l02 qemu]# bash ../qemu

Changes from V1:
* Build fixes for BOOKE (only compile tested)
* Address review feedback
