[PATCH v2 06/79] ALSA: atiixp: Allocate resources with device-managed APIs

Like the previous patch, this patch converts the resource allocations
with device-managed API calls, so that we can reduce resource-free
calls.
The atiixp drivers are simpler than intel8x0, and even the irq can be
allocated with devres.
The end result is a good amount of code reduction.
