ALSA: hda - Add function id to proc output

This patch does two things:
 Output Intel HDA Function Id in /proc/asound/cardX/codec#X
 Align Vendor/Subsystem/Revision Ids to 8 characters, front-padded with zeros

Before:
 Vendor Id: 0x11d41884
 Subsystem Id: 0x103c281a
 Revision Id: 0x100100

After:
 Function Id: 0x1
 Vendor Id: 0x11d41884
 Subsystem Id: 0x103c281a
 Revision Id: 0x0100100

As report on the Kernel Bugzilla #12888
