drm/bridge: Constify struct i2c_device_id

Browse source

'struct i2c_device_id' is not modified in these drivers.

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

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  15566	    987	     32	  16585	   40c9	drivers/gpu/drm/bridge/chipone-icn6211.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  15630	    923	     32	  16585	   40c9	drivers/gpu/drm/bridge/chipone-icn6211.o
