Add ADAU1978/ADAU1979 audio ADCs

Hendrik v. Raven requested to merge hvraven/kicad-symbols:adau1979 into master

This adds the ADAU1978 and ADAU1979 Audio ADCs from Analog Devices. They share the pinout, the measurement voltage range is different between the devices. The inputs are labelled slightly differently in the datasheet (AINxP/AINxN vs. AINx/~{AINx}).

  • I chose to place DVDD on the bottom right, as it is a power output generated from the chip, only requiring bypassing.
  • SPI functions (instead of I2C) are implemented using alternate pin functions
  • Footprint PR: kicad-footprints!2946 (merged)
