ASoC: Updates for v4.11

Another release that's mainly focused on drivers rather than core
changes, highlights include:

 - A huge batch of updates to the Intel drivers, mainly around
   DisplayPort and HDMI with some additional board support too.
 - Channel mapping support for HDMI.
 - Support for AllWinner A31 and A33, Everest Semiconductor ES8328,
   Nuvoton NAU8540.
