[PATCH net-next v2] net: lan966x: Extend lan966x with RGMII support

[Horatiu Vultur]

Extend lan966x with RGMII support. The MAC supports all RGMII_* modes.

Signed-off-by: Horatiu Vultur <horatiu.vultur@xxxxxxxxxxxxx>

v1->v2:
- use phy_interface_set_rgmii instead of setting each individual
  variant
