ASoC: Updates for v4.13

The big news with this release is the of-graph card, this provides a
replacement for simple-card that is much more flexibile and scalable,
allowing many more systems to use a generic sound card than was possible
before:

 - The of-graph card, finally merged after a long and dedicated effort
   by Morimoto-san.
 - New widget types intended mainly for use with DSPs.
 - New drivers for Allwinner V3s SoCs, Ensonic ES8316, several classes
   of x86 machine, Rockchip PDM controllers, STM32 I2S and S/PDIF
   controllers and ZTE AUD96P22 CODECs.
