Daniel Golle ee035de0fd kernel: fix mvneta Ethernet after generic phylink validate
Import patches from Linux v5.16 and v5.17 to get 2500Base-X SFP working
again with mvneta driver after the generic phylink validate backport.

Subject: [PATCH] net: mvneta: drop use of phylink_helper_basex_speed()
Now that we have a better method to select SFP interface modes, we
no longer need to use phylink_helper_basex_speed() in a driver's
validation function, and we can also get rid of our hack to indicate
both 1000base-X and 2500base-X if the comphy is present to make that
work. Remove this hack and use of phylink_helper_basex_speed().
