cannot access the GLOBAL2 register directly.
Despite the comment in code (which was misleading), the indirect access is
only used to read the switch CONFIG data from the scrap register and not
for the GLOBAL2 access.
Use the dsa data to define when the switch is in the Multi Chip Addressing
Mode (a even address different than zero).
While here fix a typo.

This patch brings 802.1q support for Marvell 88E606x ethernet switches.
Test is done on 88E6065 chip (Aterm WR1200).

- recognize ports and vlangroups based on DTS file
- support multi-chip addresing mode (required in upcoming
Armada-388-Clearfog support)
- refactor attachment function
Each port in 'dsa' node should have 'vlangroup' property. Otherwise,
e6000sw will fail to attach.

The mdio driver interface is generally useful for devices that require
MDIO without the full MII bus interface. This lifts the driver/interface
out of etherswitch(4), and adds a mdio(4) man page.

Add e6000sw driver supporting Marvell 88E6352, 88E6172, 88E6176 switches.
It needs to be attached to mdio interface, exporting SMI access
functionality. e6000sw supports port-based VLAN configuration, per-port
media changing, accessing PHY and switch registers.
e6000sw attaches miibuses and PHY drivers as children. Instead of typical
tick as callout, kthread-based tick is used. This combined with SX locks
allows MDIO read/write calls to sleep. It is expected, because this
hardware requires long delays in SMI read/write procedures, which can not
be handled by busy-waiting.
