ppc_md.calibrate_decr() is a mandatory item. Its nullity is never checked so it must be non null on all platforms. Most platforms define generic_calibrate_decr() as their ppc_md.calibrate_decr(). Have time_init() call generic_calibrate_decr() when ppc_md.calibrate_decr() is NULL, and remove default assignment from all machines.
