Takashi Iwai 529bd6c4a6 ALSA: hda - Fix PCM reconfigure 
The reconfiguration of PCM affected all PCM streams on the bus, but
this this should be done rather only for the target codec.

This patch does the following:
- introduce bitmap indicating the PCM device usages on a hda_bus
- refactor the PCM build functions
- fix __devinit prefix in some fucntions
- add a proper ifdef around HDA-reconfig-specific functions
