media: staging: atomisp: gc2235: constify acpi_device_id

Browse Source 
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

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