ALSA: cmi8330: Allocate resources with device-managed APIs
This patch converts the resource management in ISA cmi8330 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper. The remove callback became
superfluous and dropped.
This should give no user-visible functional changes.
