Marvell 88E6361 is an 8-port switch derived from the
88E6393X/88E9193X/88E6191X switches family. It can benefit from the
existing mv88e6xxx driver by simply adding the proper switch description in
the driver. Main differences with other switches from this
family are:
- 8 ports exposed (instead of 11): ports 1, 2 and 8 not available
- No 5GBase-x nor SFI/USXGMII support

---
Changes since v2:
- use direct chip info comparison instead of intermediate variable to get
  better formatting

Changes since v1:
- define internal phys offset
- enforce 88e6361 features in mv88e6393x_phylink_get_caps
- enforce 88e6361 features in mv88e6393x_port_set_speed_duplex
- enforce 88e6361 features in mv88e6393x_port_max_speed_mode

This list is ordered by the value in the register. The value you are
adding is 0x2610, which is not ordered between 0x3520 and 0x3710.
Please move this to be after the definition for
MV88E6XXX_PORT_SWITCH_ID_PROD_6250. Thanks.
