ALSA: hda: Introduce hda_codec_driver ops

Until now, we use "patch_ops" embedded in hda_codec object for
defining the callbacks that are used in various places to manage
HD-audio codec.  But from the device driver POV, this should have been
rather the driver ops, instead of the callbacks in the codec object.

This patch defines the driver ops for HD-audio codec driver as the
replacement.  We reuse the same struct hda_codec_ops, and this is put
as hda_codec_driver.ops.  When the driver->ops callbacks are defined,
they are called primarily instead of codec->patch_ops callbacks.

With converting to the driver ops, there is no need to pass the ugly
patch_ops handling in hda_device_id tables.  That is, driver_data
field of hda_device_id becomes really optional and it can be used for
passing the codec-specific data (e.g. specifying a model).

The codec entries after the conversion should be with HDA_CODEC_ID()
and co, instead of the former HDA_CODEC_ENTRY().

Once after converting all codec drivers to use driver ops, we can get
rid of codec patch_ops.
