ALSA: es1688: constify pnp_card_device_id

pnp_card_device_id are not supposed to change at runtime. All functions working with pnp_card_device_id provided by <linux/pnp.h> work with const pnp_card_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>
