Takashi Iwai 7711fb7dac ASoC: Updates for v5.4 
Quite a big update this time around, particularly in the core
 where we've had a lot of cleanups from Morimoto-san - there's
 not much functional change but quite a bit of modernization
 going on.  We've also seen a lot of driver work, a lot of it
 cleanups but also some particular drivers.
 
  - Lots and lots of cleanups from Morimoto-san and Yue Haibing.
  - Lots of cleanups and enhancements to the Freescale, sunxi dnd
    Intel rivers.
  - Initial Sound Open Firmware suppot for i.MX8.
  - Removal of w90x900 and nuc900 drivers as the platforms are
    being removed.
  - New support for Cirrus Logic CS47L15 and CS47L92, Freescale
    i.MX 7ULP and 8MQ, Meson G12A and NXP UDA1334
