Randy Dunlap f1c87fd0e6 powerpc/4xx/cpm: Fix return value of __setup() handler
[ Upstream commit 5bb99fd409 ]

__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 cpm_powersave_off().

Fixes: d164f6d4f9 ("powerpc/4xx: Add suspend and idle support")
