Subject: [PATCH 0/2] powercap/drivers/dtpm: Constify static ops structs

Constify a couple of static ops structs that are never modified, to allow
the compiler to put them in read-only memory.

The first patch constifies one powercap_zone_constraint_ops and one
powercap_zone_ops. These are only passed to powercap_register_zone()
which accepts const pointers.

The second patch constifies dtpm_ops. In order to do that, we need to add
const to an init function and in the dtpm struct, which is ok since noone
modifies the struct.

  powercap/drivers/dtpm: Constify powercap_zone_{,constraint_}ops
  powercap/drivers/dtpm: Constify dtpm_ops
