treewide: remove files for building 5.10 kernel

All targets are bumped to 5.15. Remove the old 5.10 patches, configs
and files using:

  find target/linux -iname '*-5.10' -exec rm -r {} \;

Further, remove the 5.10 include.

-Subject: [PATCH 122/247] ASoC: atmel-i2s: do not warn if muxclk is missing
-
-Besides the fact that muxclk is optional, muxclk can be set using
-assigned-clocks, removing the need to set it in driver. The warning is
-thus unneeded, so we can transform it in a debug print, eventually to just
-reflect that muxclk was not set by the driver.
