ALSA: hda - Modularize HD-audio driver
Split the monolithc HD-audio driver into several pieces:
- snd-hda-intel HD-audio PCI controller driver; loaded via udev
- snd-hda-codec HD-audio codec bus driver
- snd-hda-codec-* Specific HD-audio codec drivers
When built as modules, snd-hda-codec (that is invoked by snd-hda-intel)
looks up the codec vendor ID and loads the corresponding codec module
automatically via request_module().
When built in a kernel, each codec drivers are statically hooked up
before probing the PCI.
This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module
information for each driver, and driver-linking codes between
codec-bus and codec drivers.
TODO:
- Avoid EXPORT_SYMBOL*() when built-in kernel
- Restore __devinit appropriately depending on the condition
