ALSA: hda - make laptop-eapd model back for AD1986A

The changes specific for Samsung laptops seem unapplicable to other
hardware models like ASUS.  The mic inputs are lost on such hardware
by the change 5d5d5f43f1b835c375de9bd270cce030d16e2871.

This patch adds back the old laptop-eapd model, and create a new
model "samsung" for the new one specific to Samsung laptops with
automatic mic selection feature.
