[PATCH] soc: ti: knav_dma: make of_device_ids const.

[Arvind Yadav]

of_device_ids 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 structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
   2234	    608	      8	   2850	    b22	drivers/soc/ti/knav_dma.o

File size after constify keystone_qmss_of_match.
   text	   data	    bss	    dec	    hex	filename
   2650	    192	      8	   2850	    b22	drivers/soc/ti/knav_dma.o
