Takashi Iwai c9af753f26 ALSA: hda/realtek - Avoid superfluous COEF EAPD setups
Realtek codec driver applied the COEF setups to change the EAPD
control to the default mode (i.e. control by EPAD verbs) at the init
callback.  It works, but this is too excessive at the same time, since
it's called at each runtime PM resume.  That is, the initialization
should be done only once after the probe.  One may think that moving
this to the probe should be OK, but no -- there is a catch; when a
system resumes from S4 (hibernation), we need to re-initialize this
again manually, because it's out of regcache restoration.

This patch addresses the issue by introducing alc_pre_init() function
that performs such a task.  This is called from each codec probe
function, and it's called from the resume callback conditionally only
from S4 resume.
