i2c: rk3x: account for const type of of_device_id.data
This driver creates a number of const structures that it stores in the data field of an of_device_id array. The data field of an of_device_id structure has type const void *, so there is no need for a const-discarding cast when putting const values into such a structure. Furthermore, adding const to the declaration of the location that receives a const value from such a field ensures that the compiler will continue to check that the value is not modified. The const-discarding cast on the extraction from the data field is thus no longer needed. Done using Coccinelle.
