Armando Visconti c788aa5254 drivers/audio: Add support to ST digital microphones (MPxxDTyy) 
This driver supports ST Microelectronics digital pdm microphones
(MPxxDTyy) connected through different peripherals. Currently only
I2S is supported.

The driver makes use internally of the OpenPDM2PCM library
to convert the PDM audio stream to PCM. Currently the
oversampling factor is fixed to 64.
