net: dsa: mv88e6xxx: add a soft reset operation
Marvell chips have different way to issue a software reset. Old chips (such as 88E6060) have a reset bit in an ATU control register. Newer chips moved this bit in a Global control register. Chips with controllable PPU should reset the PPU when resetting the switch. Add a new reset operation to implement these differences and introduce a mv88e6xxx_software_reset() helper to wrap it conveniently.
