Subject: [PATCH] staging: atomisp: lm3554: 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
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
