ALSA: azt2320: Allocate resources with device-managed APIs
This patch converts the resource management in ISA azt2320 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.
