ALSA: Echoaudio - Add suspend support #2

This patch adds rearranges parts of the initialization code and adds
suspend and resume callbacks.

This patch adds suspend and resume callbacks.
It also rearranges parts of the initialization code so it can be
used in both the first initialization (when the module is loaded we
also have to load default settings) and the resume callback (where
we have to restore the previous settings).
