'struct i2c_device_id' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig:
Before:
======
    text	   data	    bss	    dec	    hex	filename
   12136	    822	      0	  12958	   329e	drivers/gpu/drm/i2c/tda9950.o

After:
=====
    text	   data	    bss	    dec	    hex	filename
   12200	    758	      0	  12958	   329e	drivers/gpu/drm/i2c/tda9950.o
