power: reset: account for const type of of_device_id.data
This driver creates a const structure that it stores in the data field of an of_device_id array. Add const to the declaration of the location that receives a value from the data field to ensure that the compiler will continue to check that the value is not modified and remove the const-dropping cast on the access to the data field. Done using Coccinelle.
