powerpc: add Freescale hypervisor partition control functions
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; Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
