After all conversions, driver->ops became a must in most places
(except for the codec power setup which might be called before binding
to the codec driver), hence we can get rid of the superfluous
driver->ops NULL checks, too.

Now that all patch_ops usage have been converted to the new
hda_codec_ops probe, we can drop patch_ops from the hda_codec,
together with the calls of patch_ops callbacks.
The hda_codec_ops.free callback is removed as all have been replaced
with the new remove callback.
Also, correct comments mentioning "patch"; it's replaced with "codec
driver".

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.

The snd-hda-codec module contains the most of common code used by both
HD-audio controller and codec drivers, and it's basically independent
from PCI. Let's move the code to sound/hda/common directory as a part
of code reorganization.
The hda_ prefix is dropped from the most of file names as it's rather
superfluous.
