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] net: ethernet: mediatek: ppe: fix busy wait loop
-
-The intention is for the loop to timeout if the body does not succeed.
-The current logic calls time_is_before_jiffies(timeout) which is false
-until after the timeout, so the loop body never executes.
-
-Fix by using readl_poll_timeout as a more standard and less error-prone
-solution.

-Fixes: ba37b7caf1ed ("net: ethernet: mtk_eth_soc: add support for initializing the PPE")
