ASoC: Updates for v3.12

Browse Source 
- 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.

Contact: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
Description:
Maximum number of segments that the frontend will negotiate
with the backend for indirect descriptors. The default value
is 32 - higher value means more potential throughput but more
memory usage. The backend picks the minimum of the frontend
and its default backend value.
