acpi_device_id are not supposed to change at runtime. All functions
working with acpi_device_id provided by <acpi/acpi_bus.h> work with
const acpi_device_id. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  10297	   1888	      0	  12185	   2f99 drivers/staging/media/atomisp/i2c/gc0310.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  10361	   1824	      0	  12185	   2f99 drivers/staging/media/atomisp/i2c/gc0310.o

There's four more... I've applied all to my atomisp branch.

Arvind: please send the patches as a single set next time.
