ASoC: Updates for v3.15

Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:

 - Lots of cleanups from Takashi for enumerations; the original API for
   these was error prone so he's refactored lots of code to use more
   modern APIs which avoid issues.
 - Elimination of the ASoC level wrappers for I2C and SPI moving us
   closer to converting to regmap completely and avoiding some
   randconfig hassle.
 - Provide both manually and transparently locked DAPM APIs rather than
   a mix of the two fixing some concurrency issues.
 - Start converting CODEC drivers to use separate bus interface drivers
   rather than having them all in one file helping avoid dependency
   issues.
 - DPCM support for Intel Haswell and Bay Trail platforms.
 - Lots of work on improvements for simple-card, DaVinci and the Renesas
   rcar drivers.
 - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
   CSR SiRF SoC.
