Merge tag 'asoc-v4.4-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

ASoC: Last updates for v4.5

A bunch more updates for v4.5, mainly driver work:

 - More topology API enhancements from Mengdong Lin working towards
   making everything more component based and being able to specify PCM
   links via topology.
 - Large sets driver updates from Cirrus, Intel (mainly more Skylake
   support) and Renesas.
 - New driver for AMD ACP
 - Rename PCM1792a driver to be generic pcm179x
