Subject: ALSA: hda - Apply click noise workaround for Thinkpads generically

From: Takashi Iwai <tiwai@suse.de>

commit 157f0b7f6c0cc0bc88647390006e959e267a0143 upstream.

It seems that a workaround for Thinkpad T440s crackling noise can be
applied generically to all Thinkpad models: namely, disabling the
default alc269 shutup callback.  This patch moves it to the existing
alc_fixup_tpt440_dock() while also replacing the rest code with
another existing alc_fixup_disable_aamix().  It resulted in a good
code reduction.
