====================
net: dsa: mv88e6xxx: port macros cosmetics

This patch series brings no functional changes.

It prefixes all common port registers macros with MV88E6XXX_PORT.
If registers or some bits differs between switch models, a reference
model is chosen (e.g. MV88E6390_PORT_MAC_CTL_SPEED_10000.)

The register names are documented as found in the datasheets.

Avoid BIT() and shifts defines and prefer a better representation of the
Marvell switch registers with ordered, hexadecimal, 16-bit values.
