A machine driver can register the two ops.

When a DAI link is added or removed by a component's topology, the
ASoC core can call the ops to notify the machine driver for extra
intialization or destruction.

E.g. topology can create FE DAI links from a cpu DAI component, and
the machine driver may define an add_dai_link ops to set machine-specific
.init ops for the DAI link.

Implement a dai link list for the soc card.

Add APIs to add/remove a DAI links dynamically, e.g. by topology.

And a dobj is embedded into the struct snd_soc_dai_link. Topology can
use the dobj to find the links created by it and remove them when the
topology component is unloaded.

The predefined DAI links are reserved to keep backward compatibility.
And they will also be added to the list.

Currently the number of DAI links is statically defined by the machine
driver at build time using an array. This makes it difficult to shrink/
grow the number of DAI links at runtime in order to reflect any changes
in topology.

We can change the DAI link array in the core to a list so that PCMs and
FE DAI links can be added and deleted at runtime to reflect changes in
use case and DSP topology. The machine driver can still register DAI links
as an array.

As the 1st step, this patch change the PCM runtime array to a list. A new
PCM runtime is added to the list when a DAI link is bound successfully.

Later patches will further implement the DAI link list.

More:
- define snd_soc_new/free_pcm_runtime() to create/free a runtime.
- define soc_add_pcm_runtime() to add a runtime to the rtd list.
- define soc_remove_pcm_runtimes() to clean up the runtime list.

- traverse the rtd list to probe the link components and dais.

- Add a field "num" to PCM runtime struct, used to specify the device
  number when creating the pcm device, and for a soc card to access
  its dai_props array.

- The following 3rd party machine/platform drivers iterate the rtd list
  to check the runtimes:
  sound/soc/intel/atom/sst-mfld-platform-pcm.c
  sound/soc/intel/boards/cht_bsw_rt5645.c
  sound/soc/intel/boards/cht_bsw_rt5672.c

Vendor drivers no longer access a DAI link's runtime by the link index
but by matching the link name via snd_soc_get_pcm_runtime(). We assume
each DAI link has a unique name.

This is preparation for changing runtimes from an array to a list later.

The patch adds the HWEQ function for the speaker output. User can set the
HWEQ parameters using the ALSA binary control byte-by-byte. We use the
following struct array to store the HWEQ parameters for implementing as
simple as possible.
struct rt5645_eq_param_s {
	unsigned short reg;
	unsigned short val;
};
It supports the variant length of the HWEQ parameters that are required.
We add the validating function in the function "rt5645_hweq_put" of the
ALSA binary control to avoid the user that puts the invalid parameters.
In the HWEQ enable function of speaker event, we also add the validating
function to prevent that the invalid parameters are applied to codec.
The HWEQ parameters should be controlled by DAPM for a specific sequence,
so the parameters will be applied to the codec in the speaker power up
event of DAPM, and will be disabled in the speaker power down event of
DAPM.

While we are at it also change the type of the rates array from u32 to
