We have snd_soc_dai/dai_stream/component_active() macro
This patch uses it.

There is no big difference at implementation for .suspend/.resume
between DAI driver and Component driver.
But because some driver is using DAI version, thus ALSA SoC needs
to keep supporting it, hence, framework becoming verbose.
If we can switch all DAI driver .suspend/.resume to Component driver,
we can remove verbose code from ALSA SoC.
Driver is getting its private data via dai->dev.
But dai->dev and component->dev are same dev, thus, we can convert
these. For same reason, we can convert dai->active to
component->active if necessary.
This patch moves DAI driver .suspend/.resume to Component driver

When transitioning to supend state, uniphier_aio_dai_suspend() is called
and asserts reset lines and disables clocks.
However, if there are two or more DAIs, uniphier_aio_dai_suspend() are
called multiple times, and double reset assersion will cause.
This patch defines the counter that has the number of DAIs at first, and
whenever uniphier_aio_dai_suspend() are called, it decrements the
counter. And only if the counter is zero, it asserts reset lines and
disables clocks.
In the same way, uniphier_aio_dai_resume() are called, it increments the
counter after deasserting reset lines and enabling clocks.

This patch adds controllers for digital volume of PCM output. Volume
effects simply linear, not dB scale as follows:
Gained PCM = Original * 0x4000 / Volume
The value range of volume is from 0x0001 to 0xffff. 0x0000 works as
mute. Initial value is 0x4000 (+0dB).

This patch adds syscon property for specifying soc-glue core.
Currently, soc-glue core is used for changing the state of S/PDIF
signal output pin to signal output state or Hi-Z state. After
resetting of SoC Hi-Z state is selected. This driver set to signal
output state when syscon property is available.

The check of blk_id == AUD_CLK_IO is redundant as it also being performed
in the following switch statement with the same return of -ENOTSUPP. Fix
this by removing the redundant comparison.
