Subject: mlxsw: spectrum_acl: Convert flower-based mirroring to new SPAN API
Patch-mainline: v5.8-rc1
Git-commit: 7240db69c332f6625da044b048d06839ab0c2649
References: bsc#1176774

In flower-based mirroring, mirroring is done with ACLs and the SPAN
agent is not bound to a port. Instead its identifier is specified in an
ACL action.

Convert this type of mirroring to use the new API.
