ALSA: hda_intel: apply the Seperate stream_tag for Skylake

commit d6795827bd79b28fef1abdaf7e525fcca506b831 upstream.

The total stream number of Skylake's input and output stream
exceeds 15, which will cause some streams do not work because
of the overflow on SDxCTL.STRM field if using the legacy
stream tag allocation method.

This patch uses the new stream tag allocation method by add
the flag AZX_DCAPS_SEPARATE_STREAM_TAG for Skylake platform.
