[RFC PATCH net-next 12/12] net: dsa: mt7530: move lowering port 5 RGMII driving to mt7530_setup()

[arinc9.unal at gmail.com]

From: Arınç ÜNAL <arinc.unal at arinc9.com>

Move lowering Tx driving of rgmii on port 5 to right before lowering of Tx
driving of trgmii on port 6 on mt7530_setup().

This way, the switch should consume less power regardless of port 5 being
used.

Emphasise on the "should".
