[cip-dev][isar-cip-core][PATCH 1/2] conf/machine: Add KERNEL_DEFCONFIG_VERSION to select defconfig path

["Quirin Gylstorff" <quirin.gylstorff@siemens.com>]

[-- Attachment #1: Type: text/plain, Size: 4371 bytes --]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

The repository cip-kernel-config[1] contains for each supported kernel
version its own directory. Add the variable KERNEL_DEFCONFIG_VERSION
to select the defconfig matching the kernel version.

Also add a version to select the rt configuration of [1].
