rtc: constify rtc_class_ops structures
Check for rtc_class_ops structures that are only passed to
devm_rtc_device_register, rtc_device_register,
platform_device_register_data, all of which declare the corresponding
parameter as const. Declare rtc_class_ops structures that have these
properties as const.
The semantic patch that makes this change is as follows:
