soc/intel/common: Add Intel HDA common block driver

There is common HDA code in soc/intel/common that provides generic
HDA support functions, but it does not provide a driver.

This change adds a common block driver for HDA that provides a
ramstage driver for SOCs that need to initialize an HDA codec.

This was tested on a board with an HDA codec to ensure that it
properly detected it and ran the codec init steps.
