But, no driver which has bus_control has DAI driver suspend/resume

Historically, CPU and Codec were implemented different, but now it is
merged as Component.
ALSA SoC is supporting suspend/resume at DAI and Component level.
The method is like below.
1) Suspend/Resume all CPU DAI if bus-control was 0
2) Suspend/Resume all Component
3) Suspend/Resume all CPU DAI if bus-control was 1
Historically 2) was Codec special operation.
Because CPU and Codec were merged into Component,
CPU suspend/resume has 3 chance to suspend(= 1/2/3), but
Codec suspend/resume has 1 chance (= 2).
Here, DAI side suspend/resume is caring bus-control, but no driver
which is supporting suspend/resume is setting bus-control.
This means 3) was never used.
Here, used parameter for suspend/resume component->dev and dai->dev are
same pointer.
For that reason, we can merge DAI and Component suspend/resume.
One note is that we should use 2), because it is caring BIAS level.
This patch removes 1) and 3).

At the moment playback_active and capture_active are using only 1 bit so
the maximum active count is 1.
However, snd_soc_runtime_activate() may be called several time on the
same dai. This happens when a dai is part of several dai_links. It is
often the case for "snd-soc-dummy-dai".
This is a problem if snd_soc_runtime_activate() is called an even number
of times on a dai. In this case the active count overflow back to 0. As
consequence, ASoC functions, such as soc_dpcm_runtime_update(), won't run
correctly.
Storing these usage counts on plain 'unsigned int' solves the problem.

Setting the ac97_control field on a CPU DAI tells the ASoC core that this
DAI in addition to audio data also transports control data to the CODEC.
This causes the core to suspend the DAI after the CODEC and resume it before
the CODEC so communication to the CODEC is still possible. This is not
necessarily something that is specific to AC'97 and can be used by other
buses with the same requirement. This patch renames the flag from
ac97_control to bus_control to make this explicit.
While we are at it also change the type from int to bool.

DAI link assumes a one to one mapping between CPU DAI and CODEC. In
some cases, the same CPU DAI can be connected to several codecs.
This is the case for example, if you connect two mono codecs to the
same I2S link in order to have a stereo card.
The current ASoC implementation does not allow such setup.
Add support for DAI links composed of a single CPU DAI and multiple
CODECs. Sound cards have to pass the CODECs array in the corresponding
DAI link through a new 'snd_soc_dai_link_component' struct. Each CODEC in
this array is described in the same manner single CODEC DAIs are
(either DT/OF node or codec_name).
Multi-codec links are not supported in the case of CODEC to CODEC links.
Just print a warning if it happens.

For some CPU/CODEC DAI devices the TDM slot infomation maybe needed. This
patch adds the slot parsing from DT supports.
TDM slot properties:
dai-tdm-slot-num : Number of slots in use.
dai-tdm-slot-width : Width in bits for each slot.
For instance:
dai-tdm-slot-num = <2>;
dai-tdm-slot-width = <8>;
And for each spcified driver, there could be one .of_xlate_tdm_slot_mask()
to specify a explicit mapping of the channels and the slots. If it's absent
the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the
tx and rx masks.
For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit
for an active slot as default, and the default active bits are at the LSB of
the masks.
