As a previous patch put all external boost devices into safe mode from reset, all external boost devices can be handled in the same way for stream open and close. The only difference is that devices without an VSPK switch can not be put in reset and devices with it can be put into reset if a configuration is applied. The function cs35l41_hda_safe_reset is created to handle the safe reset of the chip, and as systems without VSPK switch are not supported anymore, only the CS35L41 HDA driver should check its return.
