As the upcoming release will be based on Linux 5.10 only, remove all

There were no targets still actively using Linux 5.4.

-Subject: [PATCH] net: mscc: ocelot: convert to use
- ocelot_port_add_txtstamp_skb()
-
-Convert to use ocelot_port_add_txtstamp_skb() for adding skbs which
-require TX timestamp into list. Export it so that DSA Felix driver
-could reuse it too.
