Static structure fsl_otg_initdata, of type fsl_otg_config, is used only
once, when the value of its field otg_port is assigned to another
variable. As fsl_otg_initdata.otg_port is of type u8, any changes to
its copy do not affect the original, and fsl_otg_initdata itself is
never modified. Hence make fsl_otg_initdata constant to protect it from
unintended modification.
Issue found with Coccinelle.
