This adds support for the PCM1795 and the PCM1796 to the pcm179x driver.

The PCM1795 is register compatible with the PCM1792A, but it encodes two
of the register 18 FMT[2:0] values differently, so the format encoding is
described with a per-codec table instead of the width switches. Only the
PCM1795 has real 32-bit formats; on the PCM1792A and the PCM1796 a 32-bit
container keeps the 24-bit code, as it always has. Left-justified, which
the driver accepted but never programmed, is added on the way.

This series is based on a work done in 2016 by my collegue:
