Takashi Iwai 88d8822d30 ALSA: usb-audio: Manage auto-pm of all bundled interfaces 
Currently USB-audio driver manages the auto-pm of the primary
interface although a card may consist of multiple interfaces.
This may leave the secondary and other interfaces left running
unnecessarily after the auto-suspend.

This patch allows the driver managing the auto-pm of all bundled
interfaces per card.  The chip->pm_intf field is extended as
chip->intf[] to contain the array of assigned interfaces, and the
runtime-PM is performed to all those interfaces.
