ALSA: hda/realtek - remove 3k pull low procedure

Browse Source 
This was the ALC283 depop procedure.
Maybe this procedure wasn't suitable with new codec.
So, let us remove it. But HP 15z-fc000 must do 3k pull low. If it
reboot with plugged headset,
it will have errors show don't find codec error messages. Run 3k pull
low will solve issues.
So, let AMD chipset will run this for workarround.
