Subject: [net-next PATCH v2 08/15] dt-bindings: net: dsa: qca8k: Add MAC swap and clock phase properties

Add names and decriptions of additional PORT0_PAD_CTRL properties.
Document new binding qca,mac6_exchange that exchange the mac0 port
with mac6.
qca,sgmii-(rx|tx)clk-falling-edge are for setting the respective clock
phase to failling edge.
