powerpc/idle: Fix return value of __setup() handler
__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) argument or environment
strings.
Also, error return codes don't mean anything to obsolete_checksetup() --
only non-zero (usually 1) or zero. So return 1 from powersave_off().
Fixes: 302eca184fb8 ("[POWERPC] cell: use ppc_md->power_save instead of cbe_idle_loop")
