sound fixes for 4.20-rc5

As a usual pattern, we've got relatively large updates at rc5.
- A fix for races in ALSA control user elements
- ASoC DAPM regression due to component refactoring
- A fix in error handling of ASoC iteration macro
- ASoC Intel SST Skylake kconfig fix; a new Kconfig will appear as a
  consequence, but in the end it's a good cleanup
- HD-audio and USB-audio quirks as always
- Assort of ASoC driver fixes (pcm186x, Intel cht, rockchip, pcm3060,
  rsnd, omap, wm_adsp, qcom, sunxi, stm32)
