net: dsa: remove legacy_pre_march2020 detection

Browse Source 
All drivers are now updated for the March 2020 changes, and no longer
make use of the mac_pcs_get_state() or mac_an_restart() operations,
which are now NULL across all DSA drivers. All DSA drivers don't look
at speed, duplex, pause or advertisement in their phylink_mac_config()
method either.

Remove support for these operations from DSA, and stop marking DSA as
a legacy driver by default.
