[PATCH] ALSA: hda/realtek: Enable MICs of Acer SWIFT with ALC256

[Chris Chiu <chris.chiu@canonical.com>]

The Acer SWIFT Swift SF314-54/55 with ALC256 cannot detect the headset
microphone and suffers the noise problem in audio capture.

This patch enables the headset jack sense and fixes the noise problem with
aamix fixup.
