[PATCH] tpm: tpm_tis: 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
   2758    1089      10    3857     f11 drivers/char/tpm/tpm_tis.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   2854     993      10    3857     f11 drivers/char/tpm/tpm_tis.o
