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.
