ASoC: Updates for v3.12

- DAPM is now mandatory for CODEC drivers in order to avoid the repeated
  regressions in the special cases for non-DAPM CODECs and make it
  easier to integrate with other components on boards.  All existing
  drivers have had some level of DAPM support added.
- A lot of cleanups in DAPM plus support for maintaining controls in a
  specific state while a DAPM widget all contributed by Lars-Peter Clausen.
- Core helpers for bitbanged AC'97 reset from Markus Pargmann.
- New drivers and support for Analog Devices ADAU1702 and ADAU1401(a),
  Asahi Kasei Microdevices AK4554, Atmel AT91ASM9x5 and WM8904 based
  machines, Freescale S/PDIF and SSI AC'97, Renesas R-Car SoCs, Samsung
  Exynos5420 SoCs, Texas Instruments PCM1681 and PCM1792A and Wolfson
  Microelectronics WM8997.
- Support for building drivers that can support it cross-platform for
  compile test.
