This driver creates a number of const structures 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.
