ASoC: pxa: add DT bindings for pxa2xx-pcm

Browse Source 
The bindings do not carry any resources, as the module only registers
the ASoC platform driver.

DT bindings for ARM PXA2xx PCM platform driver
This is just a dummy driver that registers the PXA ASoC platform driver.
It does not have any resources assigned.
Required properties:
- compatible 'mrvl,pxa-pcm-audio'
Example:
pxa_pcm_audio: snd_soc_pxa_audio {
compatible = "mrvl,pxa-pcm-audio";
};
