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] MIPS: Add barriers between dcache & icache flushes
-
-Index-based cache operations may be arbitrarily reordered by out of
-order CPUs. Thus code which writes back the dcache & then invalidates
-the icache using indexed cache ops must include a barrier between
-operating on the 2 caches in order to prevent the scenario in which:
-
-  - icache invalidation occurs.
-
-  - icache fetch occurs, due to speculation.
-
-  - dcache writeback occurs.
-
-If the above were allowed to happen then the icache would contain stale
-data. Forcing the dcache writeback to complete before the icache
-invalidation avoids this.
