Make const v4l2_ctrl_ops structures that are only stored in a
const field or passed to a function having a const parameter.
Done with the help of Coccinelle.

The v4l2_ctrl_ops structure is only stored in the ops field of a
v4l2_ctrl_config structure, and this field is const, or passed as the
second argument of v4l2_ctrl_new_std, and the corresponding parameter
is declared as const. Accordingly, the structure can also be const.
Done with the help of Coccinelle.

The v4l2_ctrl_ops structure is only passed as the second argument to
functions such as v4l2_ctrl_new_std for which the corresponding
parameter is const, so make the v4l2_ctrl_ops structure const as well.
Done with the help of Coccinelle.
