Subject: bpf: Add lookup and update batch ops to arraymap
Patch-mainline: v5.6-rc1
Git-commit: c60f2d2861778de6370a4f4ca6ab1d7d4a32efae
References: bsc#1177028

This adds the generic batch ops functionality to bpf arraymap, note that
since deletion is not a valid operation for arraymap, only batch and
lookup are added.
