====================
net: dsa: qca8k: convert to phylink_pcs and mark as non-legacy

This series adds support into DSA for the mac_select_pcs method, and
converts qca8k to make use of this, eventually marking qca8k as non-
legacy.

Patch 1 adds DSA support for mac_select_pcs.
Patch 2 and patch 3 moves code around in qca8k to make patch 4 more
readable.
Patch 4 does a simple conversion to phylink_pcs.
Patch 5 moves the serdes configuration to phylink_pcs.
Patch 6 marks qca8k as non-legacy.

v2: fix dsa_phylink_mac_select_pcs() formatting and double-blank line
in patch 5
