Subject[PATCH] cpuidle: make sysfs attributes sysdev class attributes
These attributes are really sysdev class attributes.  The incorrect
definition leads to an oops because of recent changes which make sysdev
attributes use a different prototype.

Based on Andi's f718cd4add5aea9d379faff92f162571e356cc5f ("sched: make
scheduler sysfs attributes sysdev class devices")
