Add code to allow the ASI Tx output to be placed into High-z mode
during unused ASI cycles. This allows for other devices that may be on
the bus to drive the ASI out. By default the 320adcx140 sends 0's for

Fix the BCLK inversion for DSP modes
This is how it is defined by ASoC:
* BCLK:
* - "normal" polarity means signal is available at rising edge of BCLK
* - "inverted" polarity means signal is available at falling edge of BCLK
The adcx140 defines the BCLK edge based on coding type.
The PCM (DSP_A/B) should drive on rising and sample on falling edge, so
from ASoC pov, it is IB_NF. But from the codec pov if it is configured in
DSP mode, then the BCLK should not be inverted, defaults to the coding
standard.
For i2s, it is NB_NF from ASoC pov (drive on falling, sample on rising).
>From the codec's pov BCLK should not invert either, as this is the default
for the coding.
So, inversion must take the format into account:
IB_NF + DSP_A/B == the codec bclk inversion should be disabled
NB_NF + DSP_A/B == the codec bclk inversion should be enabled
NB_NF + I2S == the codec bclk inversion should be disabled

It was observed that if the device was active and register writes were
performed there were some unwanted behaviors particularly when writing
the word length and some filter options. So when writing to the device
the device should be placed in sleep mode and then exit sleep mode once
the register update is complete.

According to its datasheet, the digital gain should be -100 dB when
CHx_DVOL is 1 and 27 dB when CHx_DVOL is 255. But with the current
dig_vol_tlv, "Digital CHx Out Volume" shows 27.5 dB if CHx_DVOL is 255
and -95.5 dB if CHx_DVOL is 1. This commit fixes this bug.

This condition will not occur since if the dt property is not set then
the *_source variable is set to the default value. So there is no way
that *_source can be less then 0. Which is what each #define is set to.

The TLV320ADCx140 parts support Dynamic Range Enhancer (DRE) as defined
in Section 8.3.2 of the data sheets.
The DRE achieves a complete-channel dynamic range as high as 120 dB.
At a system level, the DRE scheme enables far-field, high-fidelity recording
of audio signals in very quiet environments and low-distortion recording in
loud environments.
There are 2 enables for DRE. The first is a global setting that enables
the DRE engine in the device and the other enable is per channel. If
the DRE is enabled globally then either DRE or AGC can be used per each
configured channel. If global DRE is disabled then even setting the DRE
enable bit in the channel config register will have no effect.
