When the power state of ALC283 codec goes to D3, it gives a noise via
headphone output.  This is because the driver tries to clear all pins
via snd_hda_shutup_pins().  Setting the mic pin to zero triggers such
a noise.

Define a new shutup call specific to this codec and control the pins
there more precisely.  Also, add the power-save enable/disable
sequences in the resume and the new shutup calls.
