ALSA: Echoaudio - Add suspend support #1

Move the controls init code outside the init_hw() function because is must
not be called during resume.

This patch moves the code that initializes the card's controls with
default valued from the init_hw() function into a separated
set_mixer_defaults() function (one for each of the 16 supported
cards). This change is necessary because during resume we must
resurrect the hardware without losing the previous
settings. set_mixer_defaults() must be called only once when the
module is loaded.
