ALSA: hda - Force buffer alignment for Haswell HDMI controllers
Haswell HDMI audio controllers seem to get stuck when unaligned buffer size is used. Let's enable the buffer alignment for the corresponding entries. Since AZX_DCAPS_INTEL_PCH contains AZX_DCAPS_BUFSIZE that disables the buffer alignment forcibly, define AZX_DCAPS_INTEL_HASWELL and put the necessary AZX_DCAPS bits there.
