[PATCH] KVM: PPC: booke: Use the lower four bytes while restoring guest readable SPRGs.

[PATCH] KVM: PPC: booke: Use the lower four bytes while restoring guest readable SPRGs.

[b16395]

From: Varun Sethi <Varun.Sethi@freescale.com>

While restoring the hardware copies of guest SPRG4-7 registers we must use the
the lower 4 bytes of the 64 bit sotware copies maintained by KVM.
