ASoC: Updates for v5.13

A lot of changes here for quite a quiet release in subsystem terms -
there's been a lot of fixes and cleanups all over the subsystem both
from generic work and from people working on specific drivers.

 - More cleanup and consolidation work in the core and the generic card
   drivers from Morimoto-san.
 - Lots of cppcheck fixes for Pierre-Louis Brossart.
 - New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
   accessory detection, and Realtek RT1019, RT1316, RT711 and RT715.
