cpuidle: make sysfs attributes sysdev class attributes

Browse source 
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 f718cd4add ("sched: make
scheduler sysfs attributes sysdev class devices")
