cxd56: add initial Nuttx audio driver
Adds an initial Nuttx audio driver supporting the Spresense CXD56. Being a work in progress the driver has a number of limitations: - Audio playback only, no recording yet. - Only 16 bit stereo playback is supported. - In practice only 48kHz playback is supported due to missing SRC. - Configure driver in "Device Drivers --> Audio Device Support".
