ALSA: hda/ca0132: Add extra exit functions for R3Di and SBZ
This patch adds extra functions for shutdown on the Sound Blaster Z and Recon3Di. The Recon3Di only has one specific functions, which sets the GPIO data pins to 0 to prevent a popping noise. The Sound Blaster Z exit sequence was taken from Windows. Without this exit function, the card will not reload properly unless the PC has been shutdown to clear the onboard memory. There are commented out functions currently in the sbz_exit_chip function that are added in a later patch. Also, a reboot notify function has been added, to make sure these functions are ran before a reboot. This helps when using the card through VFIO in a virtual machine, to make sure the card reloads the DSP properly.
