Christophe Leroy 0aafbdf35c powerpc: Make generic_calibrate_decr() the default
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.
