Currently the DSP loading is split into two widgets, the preloader that is a snd_soc_dapm_dai_link widget which starts a thread to download the firmware, and the DSP itself which is a snd_soc_dapm_out_drv and synchronises the thread back in to the DAPM sequence. This allows the firmware download to be overlapped with the rest of the path bring up. The use of a snd_soc_dapm_dai_link widget requires the preloader to be part of the audio path in DAPM, really a supply widget is a better fit for the preloader. The preloader is something that needs to be done for the DSP to function, not a part of the audio path itself. This change makes the DSP preloader widget a supply widget, which as well as probably being a better fit will also make it much simpler to power up the preloader widget to trigger firmware download to the core independently of the audio path coming up.
