ALSA: use card device as parent for jack input-devices

This moves the jack devices from the PCI device into the ALSA card device, which
makes it easier for userspace to find all devices belonging to a specific card
while granting access to logged-in users.

Jack input devices from sound cards can now simply be matched with udev by doing:
  SUBSYSTEM="input", SUBSYSTEMS="sound", ...

 ls -l /sys/devices/pci0000:00/0000:00:1b.0/sound/card0
 controlC0
 device -> ../../../0000:00:1b.0
 id
 input10
 input11
 input8
 input9
 number
 pcmC0D0c
 pcmC0D0p
 pcmC0D1p
 power
 subsystem -> ../../../../../class/sound
 uevent
