ASoC: Updates for v3.18

 - More componentisation work from Lars-Peter, this time mainly
   cleaning up the suspend and bias level transition callbacks.
 - Real system support for the Intel drivers and a bunch of fixes and
   enhancements for the associated CODEC drivers, this is going to need
   a lot quirks over time due to the lack of any firmware description of
   the boards.
 - Jack detect support for simple card from Dylan Reid.
 - A bunch of small fixes and enhancements for the Freescale drivers.
 - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32, Everest
   Semiconductor ES8328 and Freescale cards using the ASRC in newer i.MX
   processors.
