KVM: PPC: booke: Add watchdog emulation
This patch adds the watchdog emulation in KVM. The watchdog emulation is enabled by KVM_ENABLE_CAP(KVM_CAP_PPC_BOOKE_WATCHDOG) ioctl. The kernel timer are used for watchdog emulation and emulates h/w watchdog state machine. On watchdog timer expiry, it exit to QEMU if TCR.WRC is non ZERO. QEMU can reset/shutdown etc depending upon how it is configured.
