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.
