Some DAI components, such as HDaudio, need to be stopped in two steps a) stop the DAI component b) stop the DAI DMA This patch enables this two-step stop by expanding the DAI_CONFIG IPC flags and split them into 2 parts. The 4 LSB bits indicate when the DAI_CONFIG IPC is sent, ex: hw_params, hw_free or pause. The 4 MSB bits are used as the quirk flags to be used along with the command flags. The quirk flag called SOF_DAI_CONFIG_FLAGS_2_STEP_STOP shall be set along with the HW_PARAMS command flag, i.e. before the pipeline is started so that the stop/pause trigger op in the FW can take the appropriate action to either perform/skip the DMA stop. If set, the DMA stop will be executed when the DAI_CONFIG IPC is sent during hw_free. In the case of pause, DMA pause will be handled when the DAI_CONFIG IPC is sent with the PAUSE command flag. Along with this, modify the signature for the hda_ctrl_dai_widget_setup/ hda_ctrl_dai_widget_free() functions to take additional flags as an argument and modify all users to pass the appropriate quirk flags. Only the HDA DAI's need to pass the SOF_DAI_CONFIG_FLAGS_2_STEP_STOP quirk flag during hw_params to indicate that it supports two-step stop and pause.
