Revert "Kernel: T2843: upgrade Kernel to v5.8.5"

This reverts commit 78c43c2078e292ac9b53d2d6a41a47466d283914.

Unfortunately we must revert the Kernel upgrade as there are two problematic
issues. One which is the break of ABI functionality with parted [1] and second
the internal cryptop API [2] which removed required literals for the build of
Intel QAT acceleration.

In the two weeks running 5.8 we still learned a lot - we experienced a
performance improvement of ~30% when doing NAT @ > 10GBit/s and also utilizing
the build in updated drivers for Intel NICs and WireGuard.

We are looking forward to the release of this years LTS kernel and we hope to
ship this in the final 1.3 release.

-Subject: [PATCH] API: adjust to Linux Kernel 5.8 API
-
-Change source code to be compatible with the latest Linux 5.8 Kernel API.
-The change is not backwards compatible with the old API.
-
-Conditional checks like
- #if (LINUX_VERSION_CODE >= KERNEL_VERSION(5,5,0))
-should be added
