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
