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.
