[ALSA] au88x0 - clean up __devinit/__devexit

Modules: au88x0 driver

Removed all use of __devinit/__devexit and init.h from headers.  Any
attributes given in the prototype but not in the function definition have
been moved to the definition.

An exception is vortex_eq_free: I removed the __devexit attribute because
vortex_eq_free is called from vortex_core_shutdown, and
vortex_core_shutdown may be called from __devinit snd_vortex_create.

Compile tested with allyesconfig and allmodconfig.
