[PATCH] add hardware dependent/specific alsa sound devices to HAL

[Danny Kukawka]

Hi,

this patch adds support/detection of hardware specific ALSA Sound devices to 
HAL. The driver can use this devices freely for purposes that are not covered 
by standard ALSA API (PCM, control, etc).

Also changed alsa.device_pcm_class from mandatory to not mandatory because not 
all devices in the alsa namespace need to provide the property (e.g. if they 
aren't a PCM device).
