net: dsa: mv88e6xxx: prefix Port MAC Control macros 

For implicit namespacing and clarity, prefix the common MAC Control
Register macros with MV88E6XXX_PORT_MAC_CTL and the ones which differ
between implementations with a chosen reference model
(e.g. MV88E6065_PORT_MAC_CTL_SPEED_200.)

Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers.
