Set core_get/put() ops for TGL. When core_get() is requested for a core, its ref_count is incremented and the PM_CORE_ENABLE IPC sent to the firmware to power up the core if the current ref_count is 1. Conversely, the ref_count is decremented in core_put() and an IPC is sent to the DSP to power off the core if the ref_count is 0.
