ALSA: hda/realtek - ALC256 speaker noise issue

BugLink: http://bugs.launchpad.net/bugs/1596575

commit e69e7e03 upstream.

That is some different register for ALC255 and ALC256.
ALC256 can't fit with some ALC255 register.
This issue is cause from LDO output voltage control.
This patch is updated the right LDO register value.
