[PATCH] drivers/macintosh: make wf_control_ops and wf_pid_param const

Bhumika Goyal
Make wf_control_ops const as they are only stored in the ops field of a
wf_control structure, which is const.
Make wf_pid_param const as they are only used during a copy operation.
Done using Coccinelle.

Cross compiled windfarm_smu_controls.o and windfarm_rm31.o for powerpc.
