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
  15148    2640       8   17796    4584
drivers/staging/media/atomisp/i2c/mt9m114.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  15244    2512       8   17764    4564
