ASoC: Updates for v5.12

Another quiet release in terms of features, though several of the
drivers got quite a bit of work and there were a lot of general changes
resulting from Morimoto-san's ongoing cleanup work.

 - As ever, lots of hard work by Morimoto-san cleaning up the code and
   making it more consistent.
 - Many improvements in the Intel drivers including a wide range of
   quirks and bug fixes.
 - A KUnit testsuite for the topology code.
 - Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured
   nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro
 - Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers.
