ALSA: hda/realtek: Add headset mic quirk for Acer S40-54

Acer S40-54 with ALC256 does not restore headset mic detection properly
after S4 resume. After resume, headset plug events may no longer update
the headset mic state, leaving the headset microphone unavailable.

The system uses subsystem ID 1025:161f. Applying the existing
ALC256_FIXUP_ACER_MIC_NO_PRESENCE fixup restores headset mic detection
on this machine.

Add a machine-specific quirk for this system.
