[PATCH] staging: atomisp: lm3554: constify acpi_device_id.

[Arvind Yadav]

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
   5347	   1920	     24	   7291	   1c7b drivers/staging/media/atomisp/i2c/lm3554.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   5411	   1856	     24	   7291	   1c7b drivers/staging/media/atomisp/i2c/lm3554.o
