Subject: [PATCH 17/17] pinctrl: vt8500: constify pinconf_ops, pinctrl_ops, and pinmux_ops structures

These structures are only stored in fields of a pinctrl_desc
structure (confops, pctlops, and pmxops) that are const. Make the
structures const as well.

Done with the help of Coccinelle.

Signed-off-by: Julia Lawall <Julia.Lawall@...6.fr>
