media: dibx000_common: Constify struct i2c_algorithm

'struct i2c_algorithm' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

To do so, the prototype of i2c_adapter_init() has to be updated as well.

On a x86_64, with allmodconfig:
