ASoC: SND_SOC_DAIFMT_GATED become 0 as default settings

Current soc-dai.h defines SND_SOC_DAIFMT_GATED as (2 << 4),
but gated clock should be default settings (= 0).
This patch fixup SND_SOC_DAIFMT_GATED as (0 << 4).

ASoC: clock gating is decided by bool on snd_soc_of_parse_daifmt()

ASoC clock gate settings are continuous/gated only.
This patch decides it as bool, then, gated clock will be default.

ASoC: tlv320aic3x: Convert mic bias to a supply widget

Convert MicBias widgets to supply widget.

On tlv320aic3x, Mic bias power on/off shares the same register bits
with output mic bias voltage.  So, when power on mic bias, we need
reclaim it to voltage value.

Provide a new platform data so that the micbias voltage can be sent
according to board requirement. Now since tlc320aic3x codec driver
is DT aware, update dt files and functions to handle this new
"micbias-vg"  platform data.

Because of sharing of bits, when enabling the micbias, voltage also
needs to be updated. So use SND_SOC_DAPM_POST_PMU & SND_SOC_DAPM_PRE_PMD
macro to create an event to handle this.

Since micbias is converted to supply widget, updated machine drivers as
well.

ASoC: davinci: machine: Add device tree binding

Device tree support for Davinci Machine driver

When the board boots with device tree, the driver will receive card,
codec, dai interface details (like the card name, DAPM routing map,
phandle for the audio components described in the dts file, codec mclk
speed).
The card will be set up based on this information.
Since the routing is provided via DT we can mark the card fully routed
so core can take care of disconnecting the unused pins.

ARM: davinci: da850: add pinctrl driver entries

For DT, Davinci platform can use pinctrl-single driver for handling
Padconf registers.

Enable PINCTRL Config for all Davinci platform.  Add required
pinctrl DT entries in da850 dts file

Test procedure

 1)Populate DT file with NAND node information.
 2)Populate board DT file with pinmux information for NAND.
 3)Boot and confirm NAND is detected by the kernel
 4)Cat /proc/mtd shows up single partition.
