ASoC: ada*, ssm*: use simple i2c probe function 
The i2c probe functions here don't use the id information provided in
their second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.

This avoids scanning the identifier tables during probes.

ASoC: adau7118: Mark the ADAU7118 reset register as volatile 
Without this the previously written value was written to this reg,
which caused the different configuration registers to be reset.

ASOC: Add ADAU7118 8 Channel PDM-to-I2S/TDM Converter driver 
This patch adds support for the 8 channel PDM-to-I2S/TDM converter. The
ADAU7118 converts four stereo pulse density modulation (PDM) bitstreams
into one pulse code modulation (PCM) output stream. The source for the PDM
data can be eight microphones or other PDM sources. The PCM audio data is
output on a serial audio interface port in either inter-IC serial (I2S) or
time domain multiplexed (TDM) format.
