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.

-+Kernel driver tps23861
-+======================
-+
-+Supported chips:
-+  * Texas Instruments TPS23861
-+
-+    Prefix: 'tps23861'

-+
-+Description
-+-----------
-+
-+This driver supports hardware monitoring for Texas Instruments TPS23861 PoE PSE.
-+
-+TPS23861 is a quad port IEEE802.3at PSE controller with optional I2C control
-+and monitoring capabilities.
-+
-+TPS23861 offers three modes of operation: Auto, Semi-Auto and Manual.
-+
-+This driver only supports the Auto mode of operation providing monitoring
-+as well as enabling/disabling the four ports.
-+
