ARM: OMAP2+: 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. So mark the
non-const function parameters and structs for OMAP2+ as const, too.
