KVM: PPC: Book3S HV: Handle new LPCR bits on POWER8
POWER8 has a bit in the LPCR to enable or disable the PURR and SPURR
registers to count when in the guest. Set this bit.
POWER8 has a field in the LPCR called AIL (Alternate Interrupt Location)
which is used to enable relocation-on interrupts. Allow userspace to
set this field.
