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: cpuidle: mvebu: indicate failure to enter deeper sleep states
-
-The cpuidle ->enter method expects the return value to be the sleep
-state we entered.  Returning negative numbers or other codes is not
-permissible since coupled CPU idle was merged.
-
-At least some of the mvebu_v7_cpu_suspend() implementations return the
-value from cpu_suspend(), which returns zero if the CPU vectors back
-into the kernel via cpu_resume() (the success case), or the non-zero
-return value of the suspend actor, or one (failure cases).
-
-We do not want to be returning the failure case value back to CPU idle
-as that indicates that we successfully entered one of the deeper idle
-states.  Always return zero instead, indicating that we slept for the
-shortest amount of time.
