ASoC: cs4271: Convert to GPIO descriptors

This converts the Cirrus CS4271 ASoC codec driver to use
GPIO descriptors.

It turns out that there are two in-kernel users of the platform
data passing mechanism so these are switched over as well.

One locally defined GPIO "gpio_disabled" is declared in the
state struct but completely unused in the driver, so we delete
it.

ASoC: Drop unnecessary of_match_device() calls

If probe is reached, we've already matched the device and in the case of
DT matching, the struct device_node pointer will be set. Therefore, there
is no need to call of_match_device() in probe.

ALSA: ASoC: cs4271: add optional soft reset workaround

The CS4271 requires its LRCLK and MCLK to be stable before its RESET
line is de-asserted. That also means that clocks cannot be changed
without putting the chip back into hardware reset, which also requires
a complete re-initialization of all registers.

One (undocumented) workaround is to assert and de-assert the PDN bit
in the MODE2 register.

ASoC: codecs: Remove rtd->codec usage from CODEC drivers

In order to support CODEC<->CODEC links remove the assumption that there

# 022658be 03-Feb-2012 Liam Girdwood <lrg@ti.com>

ASoC: core: Add support for DAI and machine kcontrols.

Currently ASoC can only add kcontrols using codec and platform component device
handles. It's also desirable to add kcontrols for DAIs (i.e. McBSP) and for
SoC card machine drivers too. This allows the kcontrol to have a direct handle to
the parent ASoC component DAI/SoC Card/Platform/Codec device and hence easily
get it's private data.

This change makes snd_soc_add_controls() static and wraps it in the folowing
calls (card and dai are new) :-

snd_soc_add_card_controls()
snd_soc_add_codec_controls()
snd_soc_add_dai_controls()
snd_soc_add_platform_controls()

This patch also does a lot of small mechanical changes in individual codec drivers
to replace snd_soc_add_controls() with snd_soc_add_codec_controls().

It also updates the McBSP DAI driver to use snd_soc_add_dai_controls().

Finally, it updates the existing machine drivers that register controls to either :-

1) Use snd_soc_add_card_controls() where no direct codec control is required.
2) Use snd_soc_add_codec_controls() where there is direct codec control.

In the case of 1) above we also update the machine drivers to get the correct
component data pointers from the kcontrol (rather than getting the machine pointer
via the codec pointer).

Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
introduced the possibility to have constant DAI ops structures, yet this is
barley used in both existing drivers and also new drivers being submitted,
although none of them modifies its DAI ops structure. The later is not
surprising since existing drivers are often used as templates for new drivers.
So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
the issue altogether.

ASoC: Remove unused "control_data" field of struct cs4271_private

The control_data field is used to initialize the codec's control_data field,
but since this is also done by the snd-soc-cache core, the redundant
assignment can be removed and the field can be dropped.
