Registers of Marvell chips are organized in internal SMI devices. One of them at address 0x1C is called Global2. It provides an extended set of registers, used for interrupt control, EEPROM access, indirect PHY access (to bypass the PHY Polling Unit) and cross-chip setup. Most chips have it, but some others don't (older ones such as 6060). Now that its related code is isolated in mv88e6xxx_g2_* functions, move it to its own global2.c file, making most of its setup code static. Then make its compilation optional, which allows to reduce the size of the mv88e6xxx driver for devices such as home routers embedding Ethernet chips without Global2 support. It is present on most recent chips, thus enable its support by default.
