Stephen Rothwell 3d5d27c40f [POWERPC] Fix warning in pseries/power.c
Introduced by commit 79393fc46e
("kobject: convert pseries/power.c to kobj_attr interface").

sys_create_file takes a "struct attrbute *" not a "struct
kobj_addribute *".

arch/powerpc/platforms/pseries/power.c: In function 'apo_pm_init':
arch/powerpc/platforms/pseries/power.c:78: warning: passing argument 2 of 'sysfs_create_file' from incompatible pointer type
