Add a shim that allows using the nrfx PDM driver via the Zephyr API.
Add also missing devicetree nodes representing the PDM peripherals
in the nRF52 Series SoCs.
Extend the "nordic,nrf-pdm" binding with a new property that allows
specifying the clock source to be used by the PDM peripheral (so that
it is possible to use HFXO for better accuracy of the peripheral clock
or, in the nRF53 Series SoCs, to use the dedicated audio oscillator).

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

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.
