ALSA: hda/realtek - Fix lose hp_pins for disable auto mute

BugLink: https://bugs.launchpad.net/bugs/1837664
commit d561aa0a70bb2e1dd85fde98b6a5561e4175ac3e upstream.

When auto_mute = no or spec->suppress_auto_mute = 1, cfg->hp_pins will
lose value.

Add this patch to find hp_pins value.
I add fixed for ALC282 ALC225 ALC256 ALC294 and alc_default_init()
alc_default_shutup().
