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