5 switch

10 Marvell 88E6361 is an 8-port switch derived from the
11 88E6393X/88E9193X/88E6191X switches family. It can benefit from the
12 existing mv88e6xxx driver by simply adding the proper switch description in
13 the driver. Main differences with other switches from this
14 family are:
15 - 8 ports exposed (instead of 11): ports 1, 2 and 8 not available
16 - No 5GBase-x nor SFI/USXGMII support

21 Adapt to 5.15 since we dont have phylink_get_caps yet.
22 So, update the old mv88e6393x_phylink_validate instead.
23 Remove max_sid since 5.15 driver does not support it yet.
