Add functions to restart and halt the current partition when running under
the Freescale hypervisor.  These functions should be assigned to various
function pointers of the ppc_md structure during the .probe() function for
the board:

	ppc_md.restart = fsl_hv_restart;
	ppc_md.power_off = fsl_hv_halt;
	ppc_md.halt = fsl_hv_halt;
