media: staging: atomisp: gc2235: constify acpi_device_id

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
  10754    1360       4   12118    2f56
drivers/staging/media/atomisp/i2c/gc2235.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  10818    1296       4   12118    2f56
