mb/intel/kblrvp: Enable HD Audio for rvp3 

Enable Azalia controller, HD Audio DSP and select
the HDAudio IoBuffer Ownership for rvp3.

Check if device is enabled in HDA codec init function
to avoid failure when Azalia controller is disabled in
the devicetree.cb.

BUG=None
TEST=Build for kblrvp3, Make sure booting is fine irrespective of HDA
enable/disable.
