hal: post_proc: make definition of instance id independent

Definition of instance id is misplaced inside definition of
hardware accelerated effects in makefile. Moving definition of
instance id outside to break the dependency. When instance id
flag is disabled, it causes acdb_audio_cal_cfg_t structure size
mismatch between HAL and ACDB loader.
