audio-lnx: Rename folders to new flat structure.

Kernel audio drivers can be categorised into below folders.
asoc - ALSA based drivers,
asoc/codecs - codec drivers,
ipc - APR IPC communication drivers,
dsp - DSP low level drivers/Audio ION/ADSP Loader,
dsp/codecs - Native encoders and decoders,
soc - SoC based drivers(pinctrl/regmap/soundwire)

Restructure drivers to above folder format.
Include directories also follow above format.
