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.
