ALSA: emu10k1: Allocate resources with device-managed APIs
This patch converts the resource management in PCI emu10k1 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, the page allocations are done
with the devres helper, and the card object release is managed now via
card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.
