The TLV320ADC3001/3101 have an internal DSP, which can either be
used in various preset configurations (called "Processing Blocks"
in the data sheet), or as a freely programmable (using the
"PurePath Studio" graphical programming tool from TI) but rather
small DSP ("miniDSP").
Using the default configuration (PRB_R1) it's possible to set up
filtering using a first-order IIR, which can be useful for adding
a digital high pass filter to the signal chain, for instance.
This patch adds support for configuring the IIR filter coefficients.
The filter itself is always enabled; the default coefficients
implement a pass-through function.
