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: MIPS: ralink: manage low reset lines
-
-Reset lines with indices smaller than 8 are currently considered invalid
-by the rt2880-reset reset controller.
-
-The MT7621 SoC uses a number of these low reset lines. The DTS defines
-reset lines "hsdma", "fe", and "mcm" with respective values 5, 6, and 2.
-As a result of the above restriction, these resets cannot be asserted or
-de-asserted by the reset controller. In cases where the bootloader does
-not de-assert these lines, this results in e.g. the MT7621's internal
-switch staying in reset.
-
-Change the reset controller to only ignore the system reset, so all
-reset lines with index greater than 0 are considered valid.
