ALSA: hda: Allocate resources with device-managed APIs
This patch is an attempt to slightly simplify the resource management in HD-audio code, by using some device-managed APIs. Only a few resources like PCI enablement and PCI resources managed via devres, but most of the rest code dealing with HD-audio core stuff couldn't be changed so much, hence the changes in this patch are pretty small in the end. A special caveat is needed for the card object: we can't move the card object release into devres, because the driver is involved with the component stuff and its unregistiration doesn't work well from devres release at all.
