rtc: make of_device_ids const

Browse Source 
of_device_ids (i.e. compatible strings and the respective data) are not
supposed to change at runtime.  All functions working with of_device_ids
provided by <linux/of.h> work with const of_device_ids.  This allows to
mark all struct of_device_id below drivers/rtc const, too.
