Kernel: Add support for Intel HDA

This is an implementation that tries to follow the spec as closely as possible, and works with Qemu's Intel HDA and some bare metal HDA controllers out there. Compiling with `INTEL_HDA_DEBUG=on` will provide a lot of detailed information that could help us getting this to work on more bare metal controllers as well :^) Output format is limited to `i16` samples for now.
