powercap: constify powercap_zone_ops and powercap_zone_constraint_ops structures
The powercap_zone_ops and powercap_zone_constraint_ops structures are never
modified, so declare them as const.
Most of the actual changes adjust indentation to accomodate the const
keyword.
Done with the help of Coccinelle.
