!337 config: add initial openeuler_defconfig for devel-6.1

Merge Pull Request from: @xiexiuqi 
 
Prepare initial configs for devel-6.1 branch.

The defconfig is based on openEuler 22.03 LTS SP1,
we use this cmd to generate config files:

  cp /boot/config-5.10.0-136.12.0.86.oe2203sp1.aarch64 arch/arm64/configs/openeuler_defconfig
  make update_oedefconfig
